Thanks for any advice.
Be careful out there.
Kristina/co host Our Turn
they gave me a copy of the computer printout. It says
PO304, failed part Cyl 4 misfire, Fuel sys MODE4,Cal/LD Value 20%, Coolant temp 183Fm S-Fuel Trim 125%, L-Fuel Trim 109%, Engine Speed 787rpm, Vehicle Speed OMPH
Self-Diag Results: Failure Detected Time, *No Self Diagnostic Failure Indicated. Further testing may be required.
I hope this is the information you were referring to. As always any advice is appreciated.
best of luck

I have 97 Path Finder. About a year ago I got the check engine light on. I have since taken it to 2 dealers and about 10 times so far.
They tell me that codes indicate that there is some problem near the GAS tank/nozzle. They have tried tightening it and checking it out but they cannot find anything. They reset the codes and a week later after driving it is back. They have advised me to tighten the gas cap after filling gas but it had not helped.
The story keeps going on....
Help anybody. Please.
Thanks

Re: 92 Mazda MPV Van, V6.
Engine light came on @ 80K miles. Looked in the owner's manual and it's triggered at that milage to replace the O2 sensor. Ok, fine, replaced by me ($50). Went to local shop to reset computer (getting good now...) Shop says "Nope, we're not touching that". Huh? Mazda did a litle diddy with that and you CANNOT reset the light WITHOUT removing the total instrument panel and manually reinserting a metal screw into another socket and re-installing the instrument panel. The comuter has nothing to do with that. I checked with Mazda (yeah, sure, what does that mechanic know..)and Mazda says (Quote)"Our mechanics don't even like to do that and it will cost you $110 plus tax".
Exsqueeze me?? Choke. I will spend $160 because of a Mazda misdesign? I wrote Mazda with my complaint and their response was "We did that so you will replace the sensor".
To make a long story short, my wife has been driving with this little "Happy Face" orange light staring her in the face for 10K miles because I refuse to pay Mazda for a really goofy, and obvious $%^&$#.
and the blasted light is still on. I have already paid over $200.00 for this problem. Anyone have any ideas on what I can do myself to fix this? I even tried disconnecting the battery for 10 minutes. It went off for about a day and came back on.
Thanks in advance
I am looking for the info on retrieving the trouble codes yourself and myself and a few other mechanics are in the process of setting up webpages for retrieving codes and their definitions,unfortunatley Lexus is down the list a bit.Ask at this site and they will try and get the retrieval process for you,be specific as to what you need and why.
thadd
Your vehicle is the OBD2 system and codes are only retrievable from a scanner,but since you have had it in for the light,they should be able to tell you specifically what codes they retrieved.Once you get the codes that came up,come back and post them and we will try and help you to figure out what is going on.
is it something that must be fixed or that i can ignore (is it possible that the problem is with the sensor and not with the EGR flow)?
I had shown it to a transmission specialist who said that there is no problem that he could fix.
Then I went to an auto service expert (?) who ran diagnostics and said he fixed the problem. The problem resurfaced and he then returned the money saying he cannot fix it.
Then, I went to another service guy - he ran diagnostics, said that there is blue smoke, a couple of fixes are needed from diagnostics and that the engine looks quite older than the mileage and that a wire is grounded. He says that the engined needs to be replaced and suggested that I sell the car off.
I need your suggestion reg what could probably be the problem(s) and what I should do - whether go for another opinion or try to sell or ..
Thanks in advance.
Would appreciate any information.
Click on my username and it should show you the website address you can go to, to find them.
I suggest you keep bugging the dealer until they fix it. It will take them a few days (was told that they have to hook on to 2 different computers to confirm the code?), but it is better than driving with the check light on.
If you like, you can email me at regrag@langate.gsu.edu.
Thanks,

It just passed New jersey's inspection at an inspection station. 3 miles from the inspection station, the "service engine soon" light came on.
Is this a coinsidence, or was something triggered when the gas cap was tested for pressure.
can anyone offer some advise ?

With my experience with the check engine light on my Mirage, it's all the electronics or your emissions. Check the following parts which can cause the "check engine" light to energize:
1. Your 02 sensor-- have you replaced?
2. Your exhaust manifold -- any cracks or leaks? Have you given your engine a bath in cold weather while it's hot?
3. Your air filter sensor--is it accidentally disconnected?
4. Your engine coil -- need a new one?
5. Your power transistor--need a new one?
6. Your computer -- hear any cracking sounds? Will cost you a few hundred, but you'll be as good as new.
I have an '89 Mirage with lots of mileage. I've replaced these parts between 1997 and the present ....and what I've noticed at around this time, the electronics start to act up...I've recently replaced my alternator for the first time since I bought it at 17,000..now I think I will drive into 200, 000 miles with not problems...now I gotta fix the oil leak. This car is notorious for a faulty oil crankcase seal that seem to give way when the timing belt needs to be replaced. ..Time for a new car in couple of years, I hope.
You were correct. The speedometer has also stopped working and the code revealed this. Installed a new cable today. Thanks!
Thanks so much for the post! I'm new to all this computer stuff, and it's really great...like having a friend when you need one! I am supposed to pick it up Tuesday, but will definitely not take it till the mechanic checks this. The code came up for the EGR valve, he said....so he replaced it. But obviously that's not it. I do love the truck and want to fix it...I hope it can be done. This is a good start. Thanks so very much for the help!
What was the exact trouble code(s) it gave?Need to know what they are,it will be something like PO133 or somehing like that.Then we can go from there. If you need more help right away,click on my name and it will show you my e-mail. If I can't get you the info to get it squared away, I know someone who can.Let us know.
This one may be the EGR,but can also be the solonoid or cirucit.
All of these codes are circuit codes and may or may not be the vlave itself,some of them are highly unlikey that it is the valve itself.
P0400 Exhaust Gas Recirculation Flow Malfunction
P0401 Exhaust Gas Recirculation Flow Insufficient Detected
P0402 Exhaust Gas Recirculation Flow Excessive Detected
P0403 Exhaust Gas Recirculation Circuit Malfunction
P0404 Exhaust Gas Recirculation Circuit Range/Performance
P0405 Exhaust Gas Recirculation Sensor A Circuit Low
P0406 Exhaust Gas Recirculation Sensor A Circuit High
P0407 Exhaust Gas Recirculation Sensor B Circuit Low
P0408 Exhaust Gas Recirculation Sensor B Circuit High
Bottom line,I highly doubt that the mechanic who is doing the work knows what he is doing,either that or they are milking it for all it is worth. I hope this helps you, all of this is speculation on what you have given and without the codes to go by,it is all guess work.
I went back and re-read your posts,I can tell you,without a doubt, the EGR system is NOT causing the vehicle to shut down. I apologize,I should have caught that sooner. The EGR system will cause poor driveability but will not cause it to just shutdown. You brought your shop to parts replacers and if they knew how to do some diagnostics,they would never have replaced the EGR valve and expected it to fix it.
We can help you thru this,but I need to know th codes and then all pertenant info on when it shuts down.
Is it always at cruising speeds?
Is it when you are on a turn or anytime?
Slowing down or speeding up?
Does the electrical system act right when this happens?
Anything else you can think of.
Off the subject,what voices do you do?I read your profile and it says you do animated voices,my kids have probably seen every animation made.
Have fun.
Thanks, Opatience...so very very much!
