sounds to me like you need to take it to somebody that can "diagnose" the problem and not throw parts at it.... And, if you have replced "1 and 2 o2 sensors", why do you have an o2 sim on it????

No, its called being a Master ASE w/L1 GM tech for the last 10 years..... It sounds to me like whoever is working on it is throwing parts at it.... It needs to be "DIAGNOSED" Granted, he has more of a description of the problem then most people on here, but without looking at "hard data", it is virtually imposible to tell him what the problem is.... He said it acted up with a computer on it.. What kind of computer??? A Tech 2?? A scope?? What??? What kind of data is being looked at??? From what I am reading, it sounds like this problem is able to be duplicated.... Should be able to record when the problem starts and look at the data.....What do the plugs look like??? What is your fuel PSI??? Are all your injectors with in the spec of each other??? So, Thank you on complimenting on my "great mind".... Im sorry Im not like other hacks out there that replace parts because of a CEL.....
