Hi. Out of desperation, I have decided to join a forum like this one to see if I can fix my truck. Back in September I bought a 1988 K1500 with a near new 5.7 liter engine (installed in Feb. '10). The truck ran fairly well, but it had a problem with a very low idle when in gear. My mechanic checked it out and said the idle could only be raised with a computer, which he did. The truck ran better for a couple of days then suddenly developed a miss only noticeable when idling.
I have been a Ford man for the last 20 years, so I know very little about Chevy products and what makes them tick. So far my son and I have fixed a vacuum leak it had, checked the fuel filter, and checked the distributor cap. The vacuum leak was slight and it was coming from where the tube that goes to the brake booster is connected to the intake. The fuel filter is fine and the distributor cap looks like brand new on the inside. I don't know what else to check. I thought that maybe the problem could be the IAC, but that wouldn't make the truck miss so much.
The crazy thing about it is that the truck runs down the road just fine--plenty of power, decent gas mileage, awesome acceleration. What could be causing this miss at idle? It's to the point that I cannot drive the truck anymore because it starts missing so bad when I stop that it shuts off. I refuse to fight with a vehicle to keep it running while I am using it.
To be honest, I am so fed up with the problem that I found myself wanting to take a baseball to it and let the junk yard come get what's left after I get done. It's a good thing that I am in my 40s and have mellowed out quite a bit. That's exactly what I would have done twenty years ago after months of trying to figure out what was wrong with a vehicle. Any help would be appreciated.
BTW, the truck got all new wires and plugs when the crate engine was installed in it. I've also had to replace the alternator, two actuators for the heating system, and fix a problem with the wiring in the tail lights. You can understand my frustration with this truck. For only having it four months, it has been troublesome.
