Hi everyone , so my crx with a ls swap starting to act up on me after racing a bmw . the problem is fine at idle but when revved up to about 2000 rpm , it starts to fluctuate and just goes crazy , by crazy i mean if drops, never goes higher but drops and fluctuates . anybody have any suggestions ? i tried the dizzy , tps sensor , wires , plugs . just need some help , any ideas people ? anybody had this problem before ?

 

Clean the IAT?

 

Check all sensors. sounds like your ECU put itself into limp mode for a bad sensor or a weak sensor connection.
if it needs ohms its not getting enough, if it needs volts not getting enough.

 

i dont think its the iat but ill look into it. any ideas which sensors it could be for my ecu to be into limp mode ?

 

That's the thing you can't just replace the part and thinking it will fix it.
Cel on? Check what code is triggering
Then go from there
