This is a double post but I thought maybe this would be a better section for it. So I have been trying to get my car running right. The car was shooting lean once it started to spool up so I took out the ecu and it smelled burnt, so I invested in a new ecu and it didnt do anything different so I took off the 2.5 bar map sensor thinking maybe the map was bad, I replaced it with a 3 bar gm map sensor and changed the ecu to a 3 bar and what not. Well I started it and it was idling at 10:1. So I figured that it must just need fuel taken out so my tuner hooked it up and it wont go anymore lean. We hooked up a new tps and it still did the same thing. I have replaced everything and tried everything I can think of and nothing is working. The ecu is defenetly giving a signal cause the idle will change and everything. The injectors are 550cc. I am at a loss to what I should do and my tuner is at a loss of what it could be. Is there maybe something that we are missing. Any help is appreciated. Thanks in advance.
