You should be getting a code. Did you take it somewhere like autozone and they plug their scanner under the dash?

If you have nott already I would clean the MAF sensor.

The diagnostic port is actually under the hood on a 94-95 V8.

I agree that you should have seen a code. You said you saw no codes. Did you literally not see any codes? You should see a set of 111's (system pass).

If you still have a CEL coming on but no codes stored, check the KAM power to the PCM. If there's an issue with that wire, the puter gets forgetful.

Do you have the ability to view PIDs?

Good luck.

also try cleaning the mass air sensor, like mustangless mentioned

And don't forget the coil.

also try cleaning the mass air sensor, like mustangless mentioned

What he said on the MAF, can be an easy fix... I would have the fuel pressure verified too...kinda have to do that if your thinking its falling on its face...

What do the plugs look like?? that can clue you in to..
Tan .. normal
White... lean
Black... to rich

Did you put the spout back in??

Good luck....

I had a similar issue, and my car finally died on me. It turned out that one of the wires in the elec connector for the coil had backed out, and once I reinserted it it ran like a top.

 

[1995greenstang]

having serious issues 5.0

when the rpms get around 2800 rpm it has no power and hesistates engine sounds like its loading but no power have changed everything
plugs, wires, cap,rotor, filter.fuel filter, fuel pressure regulator. did diagnostics but no codes although they check engine light comes on but then goes back off ive messed with the timing trying to see if it was timing but its not although it will act up then rarely it will run fine for a few minutes then goes tor unning like crap again any help will be greatly appreciated

 

[mustangfan1990]

could be igintion problem. I would try the ingintion module on the side of the distributor

Mine had similar issues when I first got it. It was the fuel pump.

 

[1995greenstang]

well today i changed the coil bought an msd one found a plug wire that was cracked and arching to the header so bought new plug wires and it still is having the issue im about to throw a stivck of dynamite in it lol

 

[1995greenstang]

ya tomorrow i plan on putting a fuel pump in it and see what that does just sucks spending a few hundred bucks to figure this thing out

 

[HISSIN50]

As mentioned, MAF wire cleaning

Good luck.

HISSIN50 enquired about the code results. I don't see a response to his query

Since you seem to have replaced the basic tune-up parts, which is good, as you now have a baseline to work from

I suggest that you test again for fault codes and post the results, otherwise you are going to be just throwing $$'s away, not so good

95 gt issues

well posted a week ago
was having issues car had no power from 2600 rpm on so i changed coil ,plugs,, wires rotor,, cap, fuel pump,fuel pressure regulator,fuel filter ran diagnostics no codes well found out it was the catalitic converters so i put mac unequal length shorties on it with mac h pipe and flowmasters. well it is still doing it but not as near as bad but the problem is still there have messed with the timing and cant seem to get it to run correctly. could it be my distirbutor? the stator?
sick of buying parts im about to burn the dam thing. thanks

Two threads moved from 5.0 Tech to 94-95 Tech, and all three threads on the same topic merged into one. Creating more than one thread on a given topic is redundant, and can make isolating an issue difficult, as we may not be aware of what advice had been given previously, and what the results of the said advice were.

 

[Adam95GT]

posibly 02's does it go away at wot??? what codes are you getting now? what led you 2 the cats??

After you clean the maf try unpluging the batt. The puter remembers the readings in the old maf and unplugging the batt for bout 5 min will reset everything to new readings. Also the dizzy has been known to go out and cause issues. keep troubleshooting
