So, I'm going to look at another FC tomorrow, since I sold my last one in winter I've regretted it ever since. The car's not bad, but the guy told me over the phone that it wont rev past 3k. Everyones telling me its a bad afm but I have no clue. Any ideas? Any help would be MUCH appreciated.

Thanks!

 

It could be a bad AFM, a large grounding problem, or a bad secondary injector.

 

just a long shot but if all fails cheack the fule pump clamps in the tank on the pump itself , had that happen to me once it was embarresing lol

 

Also check the Boost/Pressure sensor. One thing you could do is disconnecting the vacuum hose at the sensor and plug it, disconnect the TPS sensor and try to rev past the 3000 RPM.

 

if its the same car i just looked at, the guy told me me it was the coils. plus he told me the car over heats. i seen a bunch of pics of the car and it looks good but never know if you can trust some people. tires looked like they got slashed. want 800 for it.
