I have a 94 5.7l Camaro. I recently had a problem of my car just dying randomly,but my Fuel pump was priming, and I had good fuel pressure. my car would die mid drive with no sputter or miss fire. It would stay dead for a few minutes then fire back up like nothing happened. So, I replaced my Ignition control module and my coil. That fixed the problem, but now my car is acting up in a completely different way. My car's rpms will drop mid drive, the engine sputters, then works, then dies. It wont start again for about an hour. I heard that a bad MAF can cause this but that it normally throws codes, but I am not getting any. Any ideas guys?
The Fuel Pump is still priming and the opti is only 6 months old.
edit: got out this morning and got her to die. She is driving liked crap and it feels like its the engine doesnt have its normal power. The car only dies when hot, and it smells like gas. Any thoughts guys ?

 

How are you checking for codes? There are a couple that will shut down the engine, but do not turn on the SES light. One of them is DTC 16 for the optical cam position sensor in the Opti.

What brand is the Optispark?

The fuel pump can heat soak and lose pressure. The PCM also shuts it down when DTC 16 sets. Have you monitored the fuel pressure while driving the car?

Have you tried unplugging the MAF sensor? When you do that, the PCM defaults to speed-density mode to calculate the mass air flow. That would allow the engine to run normally.

Is the engine stock of modified?

 

Duralast Optispark, I am not throwing any code unfortunately. I will try to test my fuel pressure then get back. All that I know so far is its not electric and that its heat related. I didn't think it was the fuel pump since it seems to prime fine but I will check it. also thanks for the help. Engine is stock, and yah I figured out that wasnt it, so It has air and spark

 

I had the same issue. Replaced all kinds of stuff.... No codes...and then swapped in a new opti. She is back to 100%.

LTXtech.com is my drug.

 

I had a similair problem with my 97 I drove it fine till I got home n came bak to move it it would turn offf wen I tried turning it on n it said maf circuit I disconnected the connection on the maf and cleaning it n ran good I was thinkin bout rewiring it since lt1s run hot it creates resistance in the electrical

highly suspect as your problem

AC Delco or Delphi opti's only

your car will run with MAF un-pluged.

 

No. Resistance is not the issue. You need 12V between the pink wire and the black/white wire at the harness connector. Then you would need a frequency (Hz) scale on your multi-meter to ckexk the signal wire. The MAF sensor signal is a variable frequency, which the PCM converts to mass air flow (grams/second) using a calibration table programmed in the PCM. The current GM made MAF sensor is not like the 3rd Gen's Bosch sensor, that produced a resistance based variable voltage..

Have you scanned it for codes? There are several for the MAF sensor. One codes sets for irrational readings, which could be caused by a dirty sensing element.

The 97 seems to be prone to break the pink wire somewhere in the harness. That would set P0100 for a static sensor reading.
