some ideas on bad LTFT's???
 

A friend brought his vette over today that has H/C with 3500 stall. It's running like shit and we a-tapped it. It didn't show half the parameters I needed it to for some reason. I have all the param's on my 98 f-body but his 98 vette had basically generic for some reason. Anyhow, I was able to log ltrims and when I looked over his logs I noticed his trims and 02's are going nuts on B1 side. B2 will be -3 and B1 is +12.3 and basically continues to run lean as hell on that side. Any idea's on obvious things to start looking at? I'm guessing a bad injector could be the culprit but was hoping to start looking at easy and obvious stuff first and work my way up the ladder. Would be helpful is a-tap would show enhanced for his vette so I could look at other stuff to help narrow it down. A-tap has been a waste of money since it picks and chooses what it wants to show. f-body I have all param's but doesn't do me much good when I'm trying to work on a vette. Efilive doesn't support either of our O/S numbers either so that's not even an option. :mad:
