Hopefully that fixes it. The codes you listed have no bearing on your issue so don't worry about them :).

I'm hoping you're right. I'll take the old girl out tomorrow for a bit and see what happens. Once I'm comfortable, I can focus on the rest of the car, and preparing for bodywork this spring.

Funny thing, I replaced the broken vacuum tube, and it ran without an issue for the rest of the day. Now, the problem is back this morning. Hesitation....missing.....But not all the time. Intermittently. It'll be there....then bam, it takes off and runs strong....then it's back.....

sounds just like what mine is doing.
unplug that egr solenoid power connector just for the heck of it.

i have stock emissions stuff operational but short belting the smog out...but,,

i plugged the egr vac line and the issue came back.  this only pops up "after" the car has slightly warmed up, then at the speeds which i am barely on the gas moving along at 35 to 45mph, its like a miss somewhere.  my codes and descriptions are not the same as yours , pointed to that earlier if you get a chance to sanity check.

i plugged the egr vac line back in and unplugged the egr control solenoid power connector which seems to cause the problem to stay away, i did find the diode across to solenoid to be shorted .

I'll do that when I go out there.

Hows the wires to your O2 sensors? No cracks, breaks, or touching the exhaust occasionally?

Since it's intermittent, makes me wonder if it's a bad wire/connector..
These things will drive a feller bat- crazy trying to trak 'em down.

They look good, and they are covered in heat sleeves. They don't have any damage. I agree , it's friggin' driving me crazy. I'd like to figure it out, but I may be forced to take the Sport to a mechanic I know.

Quick question, I would assume that with the mass air conversion you had to move over to a mass air processor?  If so that may be where the codes are different.  I am not familiar with the speed density processors as I only have the A9L's.

If you have a chip on the car it seems like the secondary fuel pump code always comes up.  Cannot remember if you have one or not but thought I would throw it out there.  I agree with the thought a few posts back about getting a remote fuel pressure gauge where you can see it when the car is under load.

The code 95 occurs when you install a mass-air EEC-IV in our cars. Mustangs had a factory second wire (circuit) going back to the fuel pump relay to confirm that the pump kicks on. Our cars never had that wire from the factory, so the computer spits out code 95. You can definitely run a wire back there and then you'd never get the code again. But that's all it's for. Just FYI.

I've had Mass Air for a few years now. It's still having the issue. Not sure what to do right now. I'm thinking.

On the last test drive, it was stumbling, hesitating and popping from the throttle body a bit, then, smooth and running great. I was going to swap the TFI, but ran out of time. Fuel pump wouldn't do that would it? TFI maybe.....


Cassity, I did unplug the EGR plug you mentioned. Going to drive it now. I'll let you know.

I was thinking about installing my 19# injectors and Mass Air  meter and seeing if there's a difference. if so, I'll know it was the Meter. If not, I can swap them back easily.
