Hey guy i've been having some trouble with me z31, it wont rev past 2000-2500 rpm like the maf is gone and is in limp mode so i've checked the ECU and its giving error code no.12 so MAF or wiring but i've done all the testing and according to that it works fine but also smells very rich and oem number on the maf is A36000029 so an 87 I think but im not sure if it matters what one it is.

Any suggestion? Thanks Mike

 

Ok im starting to think it might be the TPS its giving me some wacky number when im testing it as well as there seems to be alot of resistance between the TPS to ECU wires
