Anyway it looks like the fitting is a dorman heater hose quick connect. The only problem is that everything I look at says it is not used on this model. But I found a picture and my truck has it.

I would first suspect a problem with the crank sensor, or the circutry for the crank sensor. This sensor is used by the PCM to determine cylinder firing. It needs to be checked with a graphing meter like a snap on vantage. If there are any unusual vibrations, it will effect the sensor. If the repair shops you have been taking it too, cant figure it out, try one that is qualified.
Code is 25, ATI/high air. Is there a trouble shooting check list for this problem?
Another problem I have that started even before the water is that on occasion(every 2 months) You will get in the truck to start it and no power anywhere, the key gets locked in the ignition in the on position. Disconnecting the battery for roughly 12hours seems to do the trick. Upon reconnecting the truck acts like nothing happened. What the hell?
P.S. I want to know if there is a way to adjust the position of my gas pedal, its a couple inches lower than my brake and clutch, I just want them to macth up for easier down shifting.
Question, truck still seems to hesitate during acceleration a bit but smooths out under hard acceleration. Second, now I have a really bad fuel odor coming through the cab even with windows up and when I get out. Any thoughts out there?
I don't think I'll ever by a GM product again...at least this make and model as we put men on the moon.... and they can't give us a better product than this?
Singed,
I think I'm turning Japanese!

I have a 2002 GMC Sonoma 4x4 SLS Crew Cab. It has the V6 ("W" vin) with Automatic Trans. I have recently begun to hear an oscillating whine, or buzzing sound, that seems to be coming from the distributor. It tends to only last between 15 seconds, to maybe a minute, and then goes away. I've heard it at startup most recently, but did hear it the other day after about 10 miles of city driving. I used a mechanics stethoscope while it was running, and the sound was the loudest when i put the probe on top of the dist. cap. Any ideas ? Distributor bearing going out maybe ? (Thanks)
:confuse:
i also had a 2x4 to 4x4 actuator problem, took it to a qualified tranny shop $500. later same problem, especially in the winter time, keep that 4.3 tuned up and buy an OBD CHECKER , (a good one) do not skimp here, it will pay for itself in the end, run a scan every month, egr valve is $303 dealer, ebay $83, all prices CND.
good Luck
I put on the ODB tester and it comes back 0300 for a random misfire.
The car runs fine and has no problems at low or high speed. I have 51000 miles on a 4.3 engine. I had to replace the distributor and did a complete tune up.
Fuel pump pressure is good. Any suggestions would be appreciated.
Thanks for the info.
I have an engine vibration to the point of shaking the dash board. At speed
with the truck it all smooths out. The truck has 115k miles on it. My first thought
is that the timing chain and tensioner is worn out and changing the timing
at low RPMs.......any other ideas? Thanks
I had hoped that I would never have to pose this question, but here goes. I have developed an oil leak on my '01 S-10 4.3 2wd. 105K miles. Maintenance has been good - oil changes every 3K or so. Never more than 4K, and a lot of times less than 3K. But just recently I noticed oil underneath the truck. At first I thought it was a loose plug, but had it replaced at the last oil change. Filter is also tight. I pressure wshed the bottom of the engine to better able to tell where it is coming from and it appears to be coming from the rear of the motor between the motor and transmission.
That seems to me to be the rear main seal? I don't seem to leak very much - about 1/3 of a quart in the last 1000 miles. So it's not a major problem, but I hate having oil drip becuase now I have to watch where I park for fear of leaving a nasy spot on someone's drive.
I also switched to Mobile One on the last oil change, but I doubt that has anything to do with it. The reason I had the oil changed is I noticed oil collected on the bottom of the pan and since I was almost due anyway, took it in and made sure the plug was replaced. When I had first inspected it, that's where most of the oil was collected and so I surmised that's where my problem lay. But since changing the oil and cleaning the bottom of the engine, I still seem to be dripping.
So now I am in quest of locating and hopefully repairing the leak with out too much hassel or expense.
thanks alot
I have a 94 s-10 4.3 vortec 6cyl. engine. The exhaust is very very noxious. When i start the engine it actually isn't too bad. As it warms up the exhaust gets very rich as if there is alot of unburnt fuel. White smoke comes out of the exhaust .
The truck has been sitting awhile and the gas smelt like varnish at first. The tank sensor is not working but i have gone through the bad gas and have burnt about 2 gallons of fresh fuel.
How can i resolve this problem.
