Default Injectors
86, I installed new ijectors from Jon. At the same time I had the mannifold off for a oil leak. The injectors are larger then stock. I had 22 lbs and now I have 24 lbs. I did put a bigger cam and roller lifters last year. Jon told me that I would need to reprogram the ecm. The problem I'm having is it won't idle. Do you think the problem is the programing or do I have something else wrong.

Is the ECM tuned for the cam? If not, the larger injector and the cam may be the problem. You need to have your ECM tuned for the mods.

THE ECU HAS TO BE PROGRAMMED. The stock computer is set for a 22lb injector. The 24's are really 25.2 if your pressure is 43.5. therefor you are putting in 13.8% fuel, its just too rich. plus the added fuel on cold start will basically keep it from idleing right
