the other day after racing my friend at that track i notice that it started to bog underload but when vtec hits, it moves fine........ so after i got it home, i replaced the plugs, wires, fuel filter, and put my test pipe on and it still does it! i dont know whats going on but its really bothering me.


the motor is a z6


any help would be appreciated!

 

Do you have a vtec controller? And is it set too low?

 

no just a p28 chipped ecu and thats it.

and that was chipped about 8 months ago.

im just going to replace the injectors because it feels like its not getting fuel

 

Let us know if it gets better. I have the same problem, mines is all boogy til I hit 3k rpms.

 

ill keep you posted

 

well i fixed the problem.


the ground wire on the vtec solenoid was not hooked up to anything, so i hooked it up to a clean ground.

now my car runs really good, no more check engin light, no more bogging, no more 500rpm idle, and now i got my vtec back lol

Well I have it advanced but never had this problem. I do have a minor exhaust leak cuz I do notice that when Im under 3k rpms I hear the exhaust leak but ones im at 3k rpms I dont hear it anymore. Kinda weird. Oh my hatch started over heating and thats cuz my Rad is all messed up and old (leaks). So Imma fix that first.
Sorry to jack your thread.

 

replace your plugs, wires, fuel filter

 

thanks bro
