    I have a 98 ranger 4.0L with 130,000 miles. It recentley started making a squeeking sound while at idle,almost sounds like a belt slipping,Well it seems I have located the noise I traced the noise with a stethoscope to the back top of the intake is there anything back there that could be making this sound..Any ideas will help ..Thanks
  • ive recently started having problems with my 2000 ford ranger it is idling eratically, hard to start, isnt accelerating like it should, is runnin rich, and occasionaly tries to die on me ive done a tune up replaced all my filters, plugs, oil, tps, O2 sensors and my thermostat due to a coolant leak havent found the leak yet but it doesnt appear to be seeping into my oil yet no milky color and the truck only smokes when i first crank it up after it warms up she seems to run fine except at an idle im thinkin either my eec or my egr but would love some feedback
  • I bet the smoke when you first start it up is black or dark brown. If so, there is too much fuel entering the engine. A leaking or stuck open fuel injecter or a vaccum leak in the fuel pressure regulator diaphram will introduce excessive fuel into the engine. The easiest thing to check is the fuel pressure regulator. Pull the vac line off and look for evidence of raw fuel inside the vac line and or diaphram. Is there a check engine light on? Unfortunately, the most common is a leaking fuel injecter. To check for this you need a fuel pressure gauge. You have to pinch off or block the return fuel line. Hook up the guage and turn the key to on (run position). See if the pressure bleeds off. The pressure should be arround 35-40psi. Good luck.

    O.K. O.K. YER NOT GONNA BELIEVE THIS 1...I posted #130 "LOW POWER ALSO" .......That the B2300 4 cylinder 5 Speed Overdrive 2WD would only go 80 @ about 3000 RPM....That was about a month after I bought it.. Where I live the top speed limit is 45..... So last week on Monday the 19 of March I drove down to Washington. DC....A cool clear day with a North-Westerly flow maybe 10 or 15 MPH. There was alota traffic so I didn't really get to run, until the second hour on the road in Eastern Rhode Island which is a little hilly. On one of the hills I am going 75 as I start to climb and as I go up the hill , it is slowly gaining a bit almost to 80, going downI am up to 90 and as it levels off I am still gaining 91, 92, 93-94!! slowly it crept up to 95 on the flat and I ran for a couple of miles in the 93-95 range B4 I chicken out....and let her drop down to a safer the 65 zone I was in...And on the way back I had quite a bit of acceleration (for a 4) from 80 to 85 and was able to run at 95 for six miles---------------One more thing, The steering & handling were just as good at 100 as at 60..... That stuff about bad steering in the 90s seems 2B wrong!!! WHAT DID I DO TO IT------to get 15 MPH more on top-end??? The ONLY things that were different from "floored at 80" ....were......Change the cap from a Leer (with a sag in the roof) to an A.R.E., ditched the bedliner........and put 37 Lbs, of air in the tires, up from 30...Nothing more!! I know, I know......That could not be it....Yeah I agree, Was it Clara on the Psychics network and her over the phone Ouija Tune Up?? Naw, I don't think so..............I think that the catalytic converter was a little clogged up and the bumpy roads on the Island & the 10% Brazilian alcohol in the Extra Mart gas I use cleaned our the carbon......But I'm open 4 suggestions WTF!! Now the truck is perfect for me.........Great gas mileage, comfortable to sleep in the nice tinted windows A.R.E. cap and keeps up with 95% of the traffic...for $1500. What a deal.. My drive to DC and back--NO problems--between 75 & 95 the whole way-except cross Bronx...What do you think??? Tom
  • i have a 99 ranger and when i put it into drive it seems like it wants to stall and i wont let me gas it up to get it moveing. it will roll and eventually get up to 50 or what ever speed but on start offs it doesnt wanna move it almost feels like its going to stall. and when i put it in to reverse it like slams into it and wants to go. has anyone had this problem? i have it at a local shop and they are stumped.

    I have a 1999 Madza 6cyl. auto 4x4. I replaced the engine with a salvage motor with 50,000 miles on it. Everything is working great. Except I have a high idle all the time. Seems like the automatic choke is on and I can't pedal it down. Even after warm up its still high. When I brake you can feel the truck trying to surge ahead. My repair guy said I need a new computer chip of some kind. The cost would be about $85. Any guess what kind of chip and could I do it myself for a cheaper price?
  • i've heard that the newer models have an idle control chip but i wouldn't know anything about them. i have a 94 ranger that had the same problem but the idle speed control on it was a screw on the throttle body that was easily accessible and easy to adjust. check for that and if you don't have it then i don't know anything about the chips

    I have a 2003 ranger 4 cly 5 speed about 65,000.
    1. about once a month after driving i go to start it and it will kinda start. Engine shakes like crazy and can not keep it running. First time it did it a friend of mine who has a Mech shop put it on computer showed everything ok. Ran great again for a little over a month. Then did it again missed work had it towed to ford dealership still would only shake on starting. I wiated at dealership a couple of hours they came out and said its running fine now they did not do anything and computer showed again nothing amiss. Ford people said maybe fuel pump maybe $650 for a maybe i said no. It did it again about a month after that but this time i let it sit for about 30 minutes and cycled key on and off a few times and it started and ran fine. I am going to replace fuel filter probably not it but a place to start. Any other suggestions. 2. I have a rattled coming from left front wheel area driving me up a wall. I hear it on normal bumps in road. When i jack up front end and hit things with a rubber mallet nothing. Any help. Other than that it is a great truck i get between 25 and 28 mpg on highway. Thanks Paul

    Ok, once upon a time I read another Ranger forum, a really good one, with a lot of postings.

    For 4 Liter Rangers of about your age, there was a wide-spread problem of 'marbles in a tin can' rattle noise. But most of these were occuring at much lower milage. Some on almost new trucks, with just a few thousand miles. And some of them did seem to occur, or get worse, after an oil change.

    As far as I know, there was never much of an actual determination of what caused this. Loose wrist pins, piston apron slap, etc, etc, were talked about, but nothing was ever pinned down as the cause. Ford did not want to do much about it either, calling it 'normal'. A few people did get Ford to replace engines, and some of the replacements had the noise come back.

    The last I read about it, most people were just driving the truck, and the noise was not causeing much of a problem.

    With your somewhat high milage, I'm not sure if you have run into the same thing. About the only thing I could tell you is to stick your head under the hood and see if you can narrow down where the noise is coming from. The 'marbles in a can' noise came from deep inside the motor, the 'bottom end', such as the crank.

    You didn't put some strange oil into the truck? Did you get the correct filter?

    A bad plug wire?

    At 65,000 miles, if you have the orginial plugs and wires, it's time to replace both.

    I have a 98 ranger, 4 cyl, manual. A month ago my check engine light came on. About a week or two later the engine wouldn't return to idle speed when I pushed in on the clutch. When I push the clutch the engine hangs at about 1800 rpm for 10-15 seconds, revs a little higher, then returns to proper idle speed. It only does it on a warm day after I have been driving for a while. Otherwise the truck seems to run pretty good.

    -Get the 'codes' pulled to see why your check engine light is on.
    -Look for a floor mat on top of you accelerator pedal.
    -Clean the thottle body. There may be so much crap there that the throttle valve will not close.
    -The Idle Speed Valve may be gunked up.
    -The throttle cable may be binding.

    I have an '03 Ranger , 3.0 V6 w/ air. I replaced the tensioner pully and now I can't get the new belt back on. It is the correct belt for this engine, I have pulled the tensioner all the way back and it just won't slip over the pully. Is there a trick to this? It just seems the belt is to short by an inch or so!

    Thanks for any help,

    New to the forum here. 02 4.0 auto trans 2by. had the truck since new 54000 easy miles. in november of 06 had the oil changed at a local shop cause i was out of time. noticed after this a slight bottem end rattle til oil pressure came up if the truck had set for a couple days. when I changed the oil myself 4months latter the filter came off with out spilling a drop. this truck ALWAYS pukes a bunch out of the filter when you unscrew it. I know what the did. they used a filter with a crappy anti drain back valve or a filter that just didn.t have one. when I went back to my regular filter never heard the noise again until just a couple days ago. we had a heat wave here in havasu ( heat wave for may at least 115 degrees.) been using 5-30 like ford recomends. been thinking of going to 10-30. would think if the crappy filter caused any damage it would have reared its ugly head by now. heard a lot about 4.0 and 4.6's/5.4's having a rattle at start sometimes. I know these engines( 4.0 / V8"s) share no DNA but they both use 5-30. ford does not recomend 10-30 even in the heat of arizona. My thinking is the 10-30 won't siphon out of the bottom end as easy when the engine sits for a day or two when nothing ever cools down below 90-100 degrees at night. Any desert boys out there got some thoughts??
