I just did a swap from dx to mpfi on a 91 STD model hatch, it starts up and cranks fine, all cylinders are firing, sparking at idle. When I give it gas it seems to hesitate at about or around 3k rpms and wont go any higher, similar to a rev limiter in a way, anyone have this problem before and I need some help quick, Thanks a ton....peaCe

 

Check your fuel Injector connections, one may have come loose. Recheck all of your engine harness plugs too, to make sure they are in the right place.

 

I did that already, all the injectors fire, all wires spark...it is running on all the cylinders it just hesitates when you give it gas it won't go past 3k...

 

Something must be pluged into the wrong sensor then. Double check them. Get a reference source if you have to to check the plug wire colors so you know they are going to the right spots.

Did you switch the outside wires on the TPS?

 

what ecu are you running?

 

PG7 ecu, Yes I switched the outside wires on the TPS

 

Check distributor timing. Also i dont know if the pg7 will work correctly with your car. Do you have a check engine light on? if so what code. Also do you have a 4 door or a hatch because i have a 4 door and theyre the ****!

 

u have a crank angle sensor
check ecu and i bet u got a code 4
u gotta recheck the dizzy.. u wired the cables wrong.... maybe u got B10 and B12 crossed....

 

Did you change your distributor when you did the conversion? You need an Si or HF distributor.
