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.

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
