Coughing?

Alright I have tried almost everything to get rid of this cough when I accelarate.

It wasn't there when I took the motor out and switched the trannys cause I blew my old one out.

I've checked everything in my repair/service manual and I've even had the computer codes read and I can't figure out what's wrong.

Well this Cough you are speaking about........ is it like

Anytime you press the gas pedal?

I gotta '00 SL2 that when she was Stock had an Auto-tragic Tranny. About 6 months ago (and after blowing up like 5 Trannies) I had that
Auto-tragic swapped out for a 5 Speed, but I still have the Auto PCM.

Anytime I press the gas pedal, I get a momentary stall/hesitation. I have been told that the only way to rid myself of this is get a Stand-Alone or Manual PCM. Sooooo, now I'm saving up for a used/Junk Yard
Manual PCM outta a 3rd Gen S Series where that car had A/C & Cruise Control. Then I will get it Re-flashed to the '00 SC2 Federal Standards and all should be good.

If you are speaking about some other type of "Cough", then I dunno.

Yeah it is whenever I press the pedal, but it stops when I get over 4k rpms. It does it rarely in 1st gear also.

What you have sounds like what is happening to my car but it had a 5 speed, and I switched it out for another 5 speed.

I still have the same PCM in it, but would that be causing the problem?

Oops

I thought in you initial Post that you switched Trannies...
meaning like me, you got rid of an Auto-tragic Tranny and "switched" it with a 5 Speed.

If you had a 5 Speed and just switched it with another 5 Speed then I dunno what the prob you have. What computer codes do you have ?

I main one was crackshaft position sensor slot A was malfunctioning I've fixed all the other it's made it go away a little.

But if something was going wrong with the that sensor wouldn't it not start?

If the crankshaft position sensor is malfunctioning you need to get it fixed. My friends mustang did this and he always complained about a jolting sensation whenever he would hit the gas pedal. Mine does this currently.. anyhow he reset his Crankshaft position sensor and it fixed it completely. Just came back later.
