My car is goin nuts, it's idling around 3000 rpm, going up and down 50-100 rpm, once sounds like its running on one rotor, ticking, and then when it's warmed up, it just wants to rev to 5-6 k rpm, I turned it off before it could be any crazier. Anyone know whats wrong?

 

Check linkage since you just pulled the intake and check for any vaccume leaks, with the idle jumping like that it sounds like a misaligned TPS.

 

yea its most likely your tps

 

i dont think a bad tps setting is going to get you up to 6K RPM sounds more like the linkage is sticking open or somthing like that and the fact that it sounds like its running on one rotor may suggest a big vacume leak as well

 

The up and down idle, if the TPS adjustment does not correct it, check your timing.

 

What about the ticking? I'm checking the timing and TPS tommorow at school. I'll let ya'll know whats wrong.

 

An idle this high can only be caused by too much air getting around the throttle, prabably caused by it not fully closing. Inspect the entire throttle linkage (pedal, cable, TB) for something causig this.

This is probably just the ECU confused by the idle speed. Correct that problem and these two will probably go away too.

 

ok, it idles very lopely around 600 right now, not the TPS, got that all set. The timing is set. I'm starting to think it might be that one of the fuel injector's or spark plugs is not firing. Car has barely any power+low gas mileage.

 

Like NZ said, check for leaks after the TB. Could be somewhere on the intake manifold or inbetween the TB and Dynamic Chamber. Have a look-see.

 

I pulled the wires from the rear rotor and nothing changed, but the coils WERE arcing, so I've got spark, but no fuel to the rear rotor. I spilled some water/coolant on the resistor solenoid thingy right below the air bleed screw, could this screw it up?

 

^ I dont think so, recheck the connections on the injectors, hell if you take the UIM off put one of your old ones back in.

 

i'm using my old ones, the motor that i got was an 88 with high impedence injectors.

 

anyone?

 

I sense that this is an early model '88...

Mid-'88 was the changeover year from low impedence to high impedence injectors...just FYI...

 

they were purple injectors, don't know the year of the enginre for sure, but purple says 88 turbo

 

bump

 

tan tops are low imp

 

you also ought to check to see if you are getting power to that injecor, you also may have accidently gotten something cloged in the injecotor during reinstallation. Keep checking over stuff, you'll get it.

 

i checked for power to both primary injectors and got nothing (???) also tested the resistor solenoid and that checked out, but the leading coil reads 14.69 ohms resistance, which= bad coil, this may be causing the problem.

 

the injestors are switched by the negative i believe so make sure your checking it right, i think you should be looking for a ground to be present not power.

 

i tested them with a noid light, got nothin.
