I had posted this in the "what did you do today" thread a few days ago but maybe I can get more opinions here.
On Wednesday, I was doing my usual drive from work to home. Merging onto the highway, my car decided to, out of nowhere, puke out on as if it were starving for gas. It started backfiring/sputtering. I couldn't go past 1 - 2 inches on the accelerator or the engine would bog down to very low RPM's (but not actually die).
First thing that came to mind was the fuel pump was on its way. I just couldn't hear it because of the highway noise (I had pulled over on the shoulder by this time). Decided to shut down and start the engine back up. All perfect again. No hesitation, full acceleration is there, as smooth as can be. WTF was that!
Well, today is Friday and it hasn't happened again since the one time. I've probably put in about 50-60 miles. I will be driving about 1000 miles next week driving allover FL and now I have a bad gut feeling this will happen again.
So some ideas:
1) MAF may have snapped and gave bogus readings to the ECM
2) ECM itself is starting to go bad
3) TPS may have been involved, giving inaccurate readings to the ECM.
4) Crank sensor had a hiccup, missed a beat and threw the ECM way off.
But none of this explains how everything was back to normal after fully turning off the ignition and then restarting the car on the side of the highway.
Opinions?
edit: I never got a CEL, probably because it didn't happen long enough to register
