Dee, Float, need some help well i got the car running but its very sluggish revs very slow, checked the timing and it looks good. I understand i might have some lag due to the turbo but I know its not that. I keep fouling spark plugs out with stock injectors. I guess its fine to get me around but theres just no power. Can the ecu be in some kinda mode.. Im gonna check for codes today. thanks

Do you have your knock sensor wired up? Check your maf wiring.

pretty sure my maf wiring is right, it revs past 2500 rpm, Im gonna try to wire the knock sensor straight to the ecu.

im still yet to wire that dam knock sensor on my ca...mine still runs pretty swell, could be better tho. lil more detail on whats wrong? if ur fouling plugs from too much gas then maybe not firing in a cylinder? or a leaky injector. im just throwing things out loli got the safc2 and it has a knock sensor in it so maybe that will account for mine not having one to start with...ill let u know if anything changes

Hmmm, lazy CA, huh? Definitely check the codes and be wary of grounding issues. Bad grounds will definitely cause this problem as well. Slow revving issues do not evolve from afm issues, it can be so many little things, but at least start with the simple stuff first and we'll go from there.
