Lean code?
Which PCM did u have in it? The "Stock" pcm would have been pissed because there was no cat...the modded PCM was tuned for LS1 TB and 42lb injectors....and an XP cam...and headers....and a GenV blower.
Wouldn't have been ideal for a stock motor.
Had no idea about the misfire. Ran good when u got it, right?
Did you ever match up the plugs like I alluded? _________________ Hi, I'm Matt. I'm the resident smartass and I have fourblack children: (ok, one's only half black..)

I had the stocker in it, and it wasnt pissed at the lack of a cat, the o2 sim took care of that. Although I had to buy a new one, the one you had on it took a shit somehow. It was spitting a p0171 code (lean bank sensor 1) at me since just after I bought it, and despite changing the o2 sensor it never went away. Im assuming there was a vacuum leak somewhere. I never cared enough to fix it though since I barely drove the thing. And yeah it drove and ran fine for me after I bought it, but no I never did match the plugs. I completely forgot about that actually . Im not blaming you for anything, dont worry. I dont think the misfire started occuring until after the cold weather hit, so Im sure the plugs were just shitty from the cold air and the massive amounts of fuel being dumped to compensate for the lean condition. Eh, whatever, not my problem now, I have a fully operable, almost brand new car now that I dont have to do anything to and Im happy lol  _________________ 2000 NBM Z28 | SLP lid | Ebay LT's w/ TSP ORY | Magnaflow catback | New Era tune | Pro 5.0 | Monster Stage2 and Tick master | BMR springs/Bilstein HD's | Spohn Adj.
