So just adjusted the TPS in my 1996 mustang 4.6L V8. It's pretty much stock, just replaced some minor parts with OEM equivalent parts (like maf sensor and IAC and such). The biggest after market part I have bolted on is a Dorman intake manifold for NPI heads. Now the other day my stang died on the way home from work, pulled up to a stop light and died, and I mean the hazards didn't even work. I was able to get it off the road and got a jump from a friend. After the jump, and pulling the ground on my battery on and off a few times, I was able to drive home another 6 miles just fine. The next morning however, the engine would turn over and then dump the RPM's to below 500 and die. I then noticed revving the car before it died kept it alive and sometimes after a few low revs I was able to keep it alive at 250RPM's. Now I just replaced the altinator and battery because I thought they were the cause. But no luck. So then I drew a code for a TPS and adjusted the it and it runs like a dream now. The only thing that bugs me is that in drive or reverse, the car idles steady at 500 even. But In park or nuetral, idles around 850 or so. I'm lost as to why it idles so low in drive. Its not a rough idle however, everything's smooth. I just don't like to see that kind of little stuff wrong with my car and I'm at a loss of how to fix it. On a side note my Bluetooth obdii plug in (dash command) shows that the catalyst, o2 reading and o2 heating Ran incomplete monitoring (not to be confused with unsupported) just curious as to what the f*** is goin on. Please help me
