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.
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 ****.
