Major Problem

[integrags91]

I have had my 91 indegra for about a year and have a few problems with, i have swapped the motor, computer, distibuter, injectors, altenator, master cylinder, and power steering. but now i have a problem and have no idea what its doing.

when i start my car it will idle at 500 rpms, fighting to do that much then vibrate a lot then die, sometimes it will idle nomarlly and can be driven but you can't go more than halfway on the trottle below 2500 rpms or it will cease to accelerate and slow the motor till it dies. i think the trottle postion sensor might be bad because i can disconnect it and everything stays the same, but i have felling that there is more to it than that.

please help

what motor are you running and what ecu are you running, did you do a vtec swap? sometimes the wires on the ecu may be a little different, when you convert you have to be careful on the wiring.

it is all stock except for the air intake, but that has been on since i got the car and never had problem with it, motor and ecm are for 91 gs
