94 GT is having some major issues. The car will turn over, start and then die, but if i give it gas it will stay lit and after about a minute it will idle. But after that the car has absolutely no power when i try to drive. It sounds like its backfiring on the 1-4 cylinder bank, and it wont rev much over 3000. I ran my codes and got that the engine coolant temp was above or below expected, replaced the water temp sensor and still the same thing. Along with that i got a code "unable to control RPM's during high RPM check"

Car is heavily modified and I have a tweecer unit. but the RPM code is there with the tweecer on or not, and the condition of the engine is the same. I drove the car 600 miles last week and i know it runs. The throttle position sensor is also new.

Anyone, any help would be awesome,

Erik

The RPM limit code is often from the IAC not performing properly, which coincides with your cold idle issue.

I'd remove and clean the IAC.

Good luck.

I had some similar sympthoms a while back backfire, loss of power and hard start
turned out to be the stator or PIP in the distributor
good luck............

Mods are 306 W/ 10:1 compression, trick flow cam, eldelbrock maifold, ported stock heads, aluminum flywheel, shortie headers, offroad H-pipe, flowmaster catback, smog pump deleted, 24lb injectors, 65mm throttle body, BBk cold air, running a tweecer unit.

I can check the IAC, i know that with the TPS u can check the voltage to see if it is bad, any way to do that with the IAC? If so where do u attach the multimeter and do u check volts or ohms? Is there any good way to check the PIP in the distributor?


Thank you everyone,
Erik

hmmm, I checked the timing with a timing light ,and it was bouncing all over the place that's how I knew it had something to do with the distributor, I had new cap and rotor, new ignition module checked the coil with another one so I tought it had to be the PIP replaced it and everything is fine now.
btw this was on a low miles msd unit
good luck, let us know........

Well the only update i have is that it isnt the IAC, i unplugged it when it was idling and the car died, so obviously thats good. Which leaves me close to square one again.

Anything else anyone?

Im willing to bet that if you change your distributor it will fix the problem. My PIP went out a while back and thats pretty much what it did. Except it wouldnt start at all after it finally died.
