heres my problem . my cat isnt plugged because i have a test pipe and i have all the ground wire additions and i got my injectors rebuilt and still my car runs like **** after 3500 rpm. i dont understand how the car can run fine up until then and then change soo much. what am i missing?

a fuel cut defence? alot of times when the cats are removed and a test pipe is installed the car has a tendecey to over boost throwing it into fuel cut.

are u positive all the injectors are the stock sized??

if all the injectors are good, then maybe you have bad wiring to one of them



unplug the ecu and unplug the injector and check the resistance across the wire from the ecu to the injector. if its real high or open circuit, then thats your problem...











if not that then posibly a bad ecu if you have good grounds and wut not

my injectors were pulled and rebuilt and flow tested and timed to 550cc

Have you checked for vacuum leaks? Do you still have the rats nest? When I first bought my AE it had a problem like what you were describing, and it turned out to be a vacuum leak.

get a boost gauge to check what boost youre running. if it hits a specific boost when it falls on its face and its around 10psi, then its fuel cut.



I'm still leaning towards something with the injector wiring, the clips suck and if theyre broken, not on right, or the wiring is messed up youll have this problem.



and please, stop making 5 posts about the same thing. Put your whole thought process into one thread. the more detailed info you can give us in one thread the better we can assist you, believe me some of us are helpful lol.
