Engine warmup problems
HAllo Friends,
I live far away from you but still I own a Chevy k5 5,7Lit 1984 model.
I have a problem specially with cold weather ( below 5 C ) with the engine.When I start it it goes to chocke mode but when It gets out of it after a wile the engine revs start to fall and finally it turns off. ( ones I was on the way and I had trouble controling the car)
Since we dont have technicians here for this car do you know what the problem is ? Is it the heat riser or what?
Please give me a 10000 mile help!!
Thank you
John

RE: Engine warmup problems
Does your carb have an electrical connection on the top of it near the passenger side?
When was the last time you replaced your fuel filter?
Can you keep it running by pushing on the accelerator pedal?

Hallo Friend,
I havent changed it for some time i have to say that...
And about your question about the accelerator pedal ...yes when i do that then it keeps runing , it comes to life and if i stop pressing it then it goes down again..
Does that help you in some way?You have something in mind?
About the carburator I must check..

Sounds as though the idle speed may be set too low. When it is warmer, does it seem to struggle when idling?
It may also be an EGR valve problem...
I would try adjusting the idle speed a bit to see how that affects things.
Here is a link that will probably be information overload, but it is a pretty comprehensive post on thirdgen.org > Rochester E4ME Quadrajet Service Rebuild

when the car is warm everthing is ok.Very stable , no problems...What is the EGR?

RE: Engine warmup problems
Ok, then it may just be the choke needing adjusting for when it pulls off.
EGR == exhaust gas recirculation. It is an emissions device which recirculates exhaust gasses back into the intake. If this were at fault, the driveability concerns would be more significant and most likely would not stop when the engine warmed up.
