I just picked up an 89 camaro that originally had a 5.0/m5, now has 5.7/m5 runs very rough, lacks power and shows codes 33 and 45, i replaced the map sensor and it seems to run a little better, had a very bad stumble, but still is nowhere near what it should be. its a tbi setup, any thing you guys can think of might help?

 

Give all the details, is this an L05 motor? Or just a 350 that you swapped over the stock 305TBI stuff onto?

 

I didnt do the swap, i literally got this car 7 hours ago, im thinking about telling the guy i have changed my mind and want the motorcycle i swapped back. I will get the numbers off the engine.

 

Yeh, ask the guy all the information. Maybe its using the wrong injectors, or the wrong ecu

 

Yeah the guy I got it from got it from the guy who did the actual swap, supposedly it ran fine, but im not really beleiving it, im 100% confident I can get it running properly, but I traded a perfect good motorcycle for it, and i didnt really want something that would need a lot of work, the only other info I have is that the engine came from a 90 truck.
