LOL !!! disregard my last post. I was in 2 separate texting conversations with my kids and reading your thread at the same time. I'm getting to old for this .......

I'd redo your codes, as stated they should be 3 digit codes on your 95. Then, on the link dawson posted, scroll down toward the bottom and it'll list all the codes for you. Then we'll know where to go from there.

That's the "All Good" code. Did you disconnect the battery since​ your last drive. That will clear all
stored codes.

I'd take it for a spin and see if it does this yet, or throws a light. Then check codes. There should have been something stored for sure.

If none are found, then I'd give the MAF a good cleaning, inspect the wire connections very closely, do a sweep test on the TPS looking for spikes or dips in voltage readings.

What are you running for a air filter ?

157, MAF below minimum voltage

it means the computer expects to see return voltages from the MAF between a set parameter in the factory program. CEL is illuminated when that voltage is lower than or exceeds the expected limits.

Most likely causes ,, high resistance in the wiring harness or plug
Or a faulty MAF sensor.

Idling is erratic with possible thick black smoke rich smell in exhaust.

Just want you to not forget the TFI sensor. This module has been know to work intermittent and most time will not show code and screw other components up to were they will send a code. They do go bad and most auto stores have them in stock. The module is located under the air cleaner. I would advise to get a motorcraft one, I stopped buying the aftermarket crap from advance, auto, etc; they are hit or miss. Good Luck

I just figured the same problem out, my 94 GT was giving me a fit and a half. I was listening to so much chatter on this site I couldn't see the trees in the forest, I pulled the plugs and they were a almost wet look nothing like you see in a guide chart I was confused at this point people were saying all kinds of stuff.
  1. bad cylinder
  2. bad injector
  3. bad gas
  4. bad ecm
  5. bad bad bad
I went MAF sensor and cleaned it, I checked the air temp sensor (it was fine) change plugs and distributor pick up no change and no OBD1 codes. TBS really don't go bad often and IAF sensor was doing its thing. After going all through this I remembered wet plugs! What makes the ecm do what it does to have a rich mix? O2 sensor plays a big part. In a open throttle position the car ran fine no hesitation the O2 sensor doesn't control open throttle only mid range and low end. I tested O2 sensors and they seemed ok but could never get over .847 volts and sometimes not over .745 (they need .975 or better no matter what they say), DING the bell in my cheap brain went off I spent the 84 bucks for two new O2's. The car runs great!
