i just installed a cold air system made by ingine and ever since i installed it my 91 240 sx barley wants to run. it wont rev past 3k and its stuttering and bogging every time i hit the gas. i have people telling me it could be that my ecu went into safe made or something like that, how would i fix my problem.

It's got to be the MAFS or the TPS or something, some kind of sensor.

I would definitely say mafs. 3000rpms is about max without good connection.

That is true. 3000 or above the MAF goes CRAZy and your car will run like crap. Clean it out also.

MAF! I have seen this time and time again on may cars... check your MAF and surrounding couplers, piping, etc... if any air is leaking before or after the car will have some problems running, especially with a load.
