Having problems with your 1992 Chevrolet K1500 ?

After engine warm at idle in drive engine runs fine but slowly starts to loose rpm's and stumble. Sometimes will then serge above 1000rpm's. Also at cruising when giving a little gas engine will stumble to almost a stall then with a touch more pedal engine kicks into "normal operation." will trip engine light with egr valve problem.I've replaced fuel filter, injectors. TPS, EGR, EGR control syllanoid, TSS.

Answers :

This is going to sound kinda stupid but i had the same problem with my 88 earlier this winter . It could be as simple as water in your fuel. the solution would be to put HEET in the tank. I prefer the red can unless you have a diesel. I live in interior alaska and if you let your tank get below a half it will condensate inside. This sounds to simple to be true, but if you live in a cold climate it makes a big differance. Water will make it run like ****.
