Go put it on the comp and see what codes are thrown. If your missing at idle your missing when driving.

A stuck or sticking EGR valve can cause this, and is a common problem on higher mileage older cars--it will often not trigger a DTC. Another potential cause is removal of the MAF screen...

Havent seen you in a while on here! I had a mustang expert check everything and he said a lomg shot will be plugs, and he is thinking an injector is getting stuck. He unplugged them one at a time and when he got to number 4 and plugged if back up the miss stopped and slowly came back. He thinks it could be that. He checked the maf and its good. Checked the egr and its good

Sounds like a sticking injector--they can be cleaned, though you can often buy a whole set of stock injectors for less than it would cost to clean them.

I have been tapering off the Mustang forums since I sold mine, I will not be going away just cutting back...

Yeah he said it was probably staying closed a little too long. I want to supercharge in the future so I may go with 42 or 39 pound anyways
