ive read a couple posts on here where the maf got hot and poped a hole in em. alright so now u need to find anther elbow. i picked up a aluminum one for mine. i would think u could get a good aftermarket one.

 

According to the FSM DCT.18 is a problem with one of the injector driver circuits ( there is no crank signal in the 94s). The PCM will shut down the driver for that injector, and that can cause a misfire. Use NOID lights to see which injector is not working. Could be bad wiring, the injector coil itself or even the PCM. I suspect the injector.

The EGR can also cause rough idling if it stays open at idle. Check the wiring and try cleaning it up. Or replace it.

The O2 sensor showing lean could be due to a shut down injector or the EGR hanging open, or a bad O2 sensor. Most likely the injector that DCT 18 is complaining about.

The engine should be able to run with the MAF disconnected from the PCM and revert to the speed density mode using only the MAP sensor. However; if the MAF is connected, all the air going into the engine must flow through the MAF. In your case part of the air is bypassing the MAF due to the hole, and this will confuse the hell out of the PCM

 

So you're saying that the hole in my elbow would not cause a chain reaction to all of this? I ordered a cold air intake with a brand new stainless steel elbow for it, gonna try this first.

I've heard of people removing the EGR completely. How would I Go about doing this and does it hurt the car? I live in louisiana so we have no emissions test or anything like that.

Thanks for your input everyone.

 

If you remove the EGR you need to plug the opning, but the PCM will complain until it is reprogrammed to delete the EGR.

DCT 18 is your real problem, the PCM sees a problem with the circuitry to one of the einjectors and is not pulsing the bad injector. You need to find out which one is bad. You fix that problem and the engine will run much better.

 

If you remove your EGR without re-programming the PCM the timing will advance too much and could damage the engine. Here are some links to explain.

What kind of hassle is reprogramming the PCM? and who exactly can do it?

 

Pete, when i install my new CAI, what should I do as far as trying to reset codes via disconnecting battery? Is there anything that I can do to kind of "reset" the whole process?
