[QUOTE="4VFTW, post: 15916077, member: 146654"] your A/F ratioos are off bank to bank with the passenger side being quite a bit leaner, the STFT is trying to compensate but is unable to correct it. since you replaced the plugs already do a compression test with the motor warm. if that checks out try cleaning the injectors and swapping them bank to bank a relog to see if the problem moves. Your MAF lb/min shows 35 which indicates around 350hp. Also getting alot of knock in the upper RPM most likely due to running out of fuel. Is that log on your nitrous tune? 18deg timing at 6k is way low for an n/a 93 tune. [/QUOTE]
