i have a 2.4 vvt i installed intake header exhaust and high flow cat. after i installed the high flow cat i started having lots of problems lots of hesitating and stalling. i keep getting high flow eficiencey and lean bank one and maf. i then installed a regular cat and the car kept doing the same thing dont know what to do

 

smash it

 

I'm gonna stick with saying get bigger injectors that flow more fuel... also, there are apparently a few shops that can tune the 2.4 VVT... check on getting it tuned on...

 

im gonna say that i hope you did an ecu reset after all these mods...

 

unplug the battery and reset it. Might take a bit of driving for your ecu to adapt to the changes.

 

i have unplugged my battery they did reflash my ecu and i just replaced my whole stock cat system and still nothing. i just put on my stock intake and going to take it in in the morning to see whats going on. its making me really sad. i love my car but im having to many problems
