O.K. techie dudes.......I need help. Ive got a 95 LT1 from a buddies camero, It is in a Jeep CJ8, with a 4L60E.
Problem: Motor ran great except for the typical "rotten egg" smell from running rich, I recently installed Vanom's nitrous system and it would not let the system "arm" due to a rich condition, .92 volts at the O2 senser. Thats OK except now the motor runs strong (even with the rich condtion) until it gets warm, not to 190 but about 120-140, then it starts "blubbering" or stumbling. IM runnng the stock MAF but IM not running a smog pump, IM sure from reading that I need to have my 8061 ECM recalibrated, but I dont think that is the problem. Anyone got any ideas?

 

Sounds like a neat ride.Did you re-program the computer for all these changes?Are you running headers?,If so, the o2's are too cold to comuicate to the computer whats happening.They have to be heated.Hey,nobody else chimed in,and I had a few brewskees,so I hope this helps a litlle.My02(See the smile)

 

Thanks for the reply Fat...IM surprised by the lack of responces!!! IM running stock exhaust manifolds, what bugs me is that the thing ran great (except for the rich condition, which wasnt very noticable from a performance stand point with a 3500 pound car). I havent had the computer reprogrammed, Ive got a spare 8051 that I can send out, who can re-program around the So Cal area?????
