Trouble Code of P0320

Car is acting really dumb. It will start then die. It started earlier today and I drove home from work, in traffic, it died when I pulled into the garage. Checked the trouble codes and came up with one, P0320 Ignition/Dist Engine Speed Input Circuit Malfunction. Anyone have any experience with this code and where I should start looking to correct it? This car has been a three month project and I just got it running. HELP!!

I'm going to guess a crankshaft position sensor malfunction. The cam position sensor has its own code, so it wouldn't be my first guess.

Sorry about that. Car is a stock 96 Mustang GT w/auto trans. The motor was replaced with a stock 97 GT motor. Only mod to the car is an UPR o/r xpipe with mil eliminators. Replacement motor has 67xxx miles on it. Car was just finished and back on the road.

Well hell, didn't know it was a NPI car. That code obviously still applies though. You're having an ignition coil problem with #5. Swap the coil packs, reset the codes, see if the code comes back and/or the letter in the code changes.

IAC? The "starts OK but dies immediately" is a classic symptom of a faulty IAC valve.

You can try cleaning the IAC (many, many threads here on the topic) but you are better off buying an OEM Ford/Motorcraft IAC valve (i.e.--not an aftermarket part).

HTH,

if thats the case it will run if you keep your foot slightly on the gas..?

just a fyi, the pinpoint test has 64 tests in it for this code and this code can be set from numerous different sources. does it run rough or anything like that

Yes, Sir, the engine will run if you just crack the throttle. It is tricky to keep it alive and the quick solution (sometimes doesn't work) is to clean the IAC valve.

Hope you're not snowed in up there on Thanksgiving.
