I Have A 95 V6 mustang wont start. It was Running Fine untill i Burned out really quick and My engine Hesitated and rpm gauge was acting Up then Died.? and wont start anymore. except for one time after that it started and was idleing good untill i started driving and den hesitaded again and backfired and shut off any responses please help..... Changed EGR VALVE AND SPARK PLUGS

So is this the only issue your having? Is the stang hard to start cold or warm? Hard to say with what youve asked....Is your TFI newer how about your Dizzy?

You can get a free scan from Autozone, Oreilys, or Advance auto parts. This should indicate a problem. If the standard test scanner does not verify a problem, the Dealers have more advanced scanners which can capture intermittent problems.

There are so many possibilities that you need more tests to find the problem. Offhand, if this is a V6 engine, there were problems with intake Manifold runners and sandwich gaskets for 2 piece intake manifolds.

Stuck manifold runners could provide lousy low rpm performance and perfect high rpm performance just like you describe whether a V6 or V8. The 2 piece intakes were used on V6 engines and once you get above midrange in Rpm, it could run acceptably at higher Rpm.

a oil gauge reading maybe delayed until car starts and builds good oil press.Did you check for spark
was car running good before this happened? Do you have a rpm reading when cranking car?

I really think it's the TPS, (throttle positioning sensor) on the throttle body. When this sensor is defective or out of position the vehicle will idle like that and even stall. If you haven't had it scanned, you should do so, that will probably tell you the problem.

try putting water in it

No, but you can bend connecting rods with ether.

My problem was the same. It was diagnosed as needing a new Crank-shaft Sensor. Replaced it and it ran great. Very difficult to get to physically!

check for fuel, spark and compression. these are the only things needed for a engine to run

sounds like you have jumped a tooth on the timing if not timing out

I would recommend replacing your fuel filter, I also drive a V6 and after replacing my filter it really improved my milage and my car ran alot smoother. I would also recommend buying a octane fuel cleaner, that will clean out your fuel injectors if those are clogged up. If it comes down to down you may need to replace the fuel injectors, but it doesn't sound like the problem is too severe if the engine is still running which is good. I recommend not to drive until the fuel filter is replace as well as putting octane injector clearner in the gas tank. You can find the octane cleaner at Checkers for cheap.
