Chevy Venture Engine Problems

    I've got one bottle of Prestone Fuel Injector Cleaner and two bottles of STP Fuel Injector Cleaner which I intend to use as I add additional tanks of gas.

    It was the STP that I used last time, when the hitest gasoline that I added brought the gas guage up to almost full. Now its about half a tank on the guage and I just added the second STP container and went out to buy more on the theory that any sort of "miracle goop" is cheaper than a whole new engine!

    I did find something that said Techron but it said Fuel System Cleaner and did not specifically say Fuel Injector so I decided to not get it quite yet since it might not be the right stuff.

    Don't really know if its getting better or not; it ain't getting worse though and so far I ain't had to put in a new engine at a whopping 4500 dollars, so I sure thank each and everyone on this board and all who run it!

    thank you very much guys i will look into it tomorrow and agian thank you. if it is the coil do i have to replace the whole thing??????/
  • 442dude442dude Posts: 373
    There are 3 coils...without having the book in front of me, I'm pretty sure that you can replace only the bad one...

    Usually the problem isn't the coil...check other things 1st
  • fleastifffleastiff Posts: 51
    This upthread message shows a way you might use to test the coil:
    1. - Clogged or dead fuel injector...no gas=no fire...
    2. Bad coil - If you're getting fuel, I'm not convinced you're getting a good spark at cylinder # 1...if I remember right...the car idles very rough...take off the spark plug wire for cylinder # 1 and start the motor...can you tell any difference? If its no worse, maybe you've got a bad coil...

    ok thank you very much guys i wil look into it this weekend any certin plugs you guys recomend????????????
  • 442dude442dude Posts: 373
    Nothing but platinum, preferably AC-Delco - you don't want to have to change these more than once every 100,000 miles...the P/N is in the owners manual...

    Hello, I too am experiencing the exact same overheating scenario as you are.
    It is a 2002 Venture (not AWD), but I'm sure that has no impact on this issue.
    I have had my head gaskets changed twice on this vehicle already. I live in upper Ontario (Canada) and we had a cold winter here. I originally started having these symptoms last year but I thought I had problems starting the car because my gas meter was messd up ( meter seemed low, so I went home got gas, put it a few gallons and it started up!) So, they changes the gas meter. Obviously, not the problem as I've found out.. I got stranded again 2 more times before Winter. The 1st day of warm weather here (last weekend), it heated up and I had to stop the car, and it wouldn't start up after 20 minutes and in the location I was in, I had to have it towed and it started up as soon as it got off the tow truck.. Now the extended warrantly won't fix it because they don't think it's getting hot, after driving the vehicle around for 15 minutes. My dealer feels it's the head gaskets, but his hands are tied as compression tests seem normal. arrgg.. I cannot trust this vehicle at all until this is resolved.. - I am very interested to see if there are any others that have experienced this with a resolution so we all can have some evidence of support around this issue. They will change the thermostat for $400. NOT!.. Cheers.

    Oh my gosh, $400.00 for a thermostat, that is crazy!! Sorry to say I too am having the same problem too, but with NO luck on a resolution as well. I am in on any sort of support group if we can get enough people and take the matter to GM. Good luck and if you ever figure it out let me know. I know when my happens again, I am driving my van right to the dealer and say "FIX IT". I can't complain to much Ol Besty has been good to me and has never quite on me. When I notice she starts getting hot I turn my heat on in the van, I know it sounds crazy and when it's 100 degrees outside it's a killer, but it works she cools right down. So, that's what leads me to believe it is a thermostat issue and/or the water pump. Again, good luck and have a great day!

    $ 400.00 is about average for a mechanic to do the job...its almost all labor to get to it as you have to take the intake plumbing out and remove the exhaust crossover pipe just to get to it...just like most repair jobs on the Venture, parts aren't very expensive but the labor is a killer due to the way that they shoe-horned the motor in there...

    Great advice, makes sense if the gel is thickening up it would be to thick to pass, thanks I'll try that.
  • rockbazzrockbazz Posts: 7
    I suppose I agree with your comment 442dude. Just seems like a lot when I don't even know if it will resolve the issue.. we'll see what happens.. I'll be sure to post back with any up coming details.. have a great day...
  • 442dude442dude Posts: 373
    Maybe I missed something but it seems that your problem is that once the engine is warm it is hard to restart and not the engine overheating (temp needle all the way to the right)? I apologize if I missed this...

    If its hard to start when hot chances are the crankshaft position sensor is going bad...yours wouldn't be the 1st or the last, its been a common problem with GM V6 engines. If its the case, a new thermostat won't make any difference.

    ive heard tell of there being a clog in the coolant line in the throttle body causing the throttle position sensor to get fubar'd.....I wonder
