MY 5 SPEED 95 GT CHECK ENGINE LIGHT COMES ON WHEN I ACCELERATE REAL HARD.TOOK IT TO TWO DIFFERENT AUTOZONE STORES AND THE SCANNER COULD NOT READ IT.IT SAID CODE ERROR. ANY SUGGESTIONS?

Scanners from auto parts stores are crap. It's a Ford so take it to a Ford dealer. They will put an NGS on it and find the problem fast. FYI though, when a diag tool cant communicate with the PCM, its may mean that the PCM is toast.

AND TURN OFF YOUR CAPS LOCK ITS HARD TO READ!!!!!

Yep, sometimes a code can have an error or be undefined with cheaper models. I would have a Ford dealer scan it like previously mentioned, hopefully it isn't toast though. Also, any exhaust mods? And when was the last tune up? Can you tell if anything is happening under acceleration, does it feel different?

The reason it's reading "error" is because your car is a 95. The scanners they lend you are OBDII scanners for 96+. You need an OBDI scanner. Usually auto stores do not have these to lend.

^ the connection for obd1 is different than obd2 so he had to have used an obd1 scanner

I replaced the rotor,cap,and plugs ,fired it up and it had a rough idle.Took around the block and it cleared up,but when I got back,I let run at idle and it was smooth for about 3min,then rough idle and check engine light.Any suggestions?

Not true. There are cars that have (16 pin) connectors OBD2 but have (12 pin) connector OBD1 hook ups/systems. (4 of the pins are blank) An OBD2 plug will fit an OBD1 connector and vice versa.

They all used obdII scanner.It is a 16 pin connector and I see only 6 pins being used.Manufactured 07/95.
