Ok, ive got an 87 K10 with a 350 tbi/700r4. Ive had problems ever since i bought it. It drove great for 2 days and started messing up. It would run real rough...die suddenly and would be hard to start. Then it wouldnt start. Ive since got it running good after replacing the engine computer, tps sensor, iac valve, and new injectors.
Starts and runs fine but it will die when i stop or slow down. Wont usually start until i hit the brakes or turn the wheel, but it wont do it a cruising speeds just slow speeds or stopping. Ive checked all my vacuum lines. I didnt notice any leaks or cracks in the hoses. I pulled the line off the brake booster thinking that was it...but nope. My pcv valve is good. It also has a fairly new fuel filter. It does have a little miss at idle but driving down the road you dont notice it at all...has good power still.
Could it be something in the emissons? Or could it be a weak fuel pump? Please help!!! Its driving me crazy and I'm pulling my hair out!..lol
