Please help. I need a mustang ~GOD~ to get this figured out !!!

[MSTANGfromSN]

I'm totally at wit's end with my 86,I'm totally out of ideas. Please help me!

I'll try to keep this short.

Awhile back this started as a hesitation
going to WOT. It was 8-10 second delay, it has slowly progressed into a miss/stumble.

I have check & cleared codes multiple times
These codes include
82
31
32
21

None of these codes exist any longer. I replaced the ECT the AM2 selonoid & the egr was sticking which mow moves freely.

The engine won't run worth doo doo, I lost 4 mph in the 1/4 mile from last year. It smells
pig rich, & has a total lack of power.

During this period I also fail emmissions
miserably (no surprise there) but I registered 9 times the limit of HC.

Plugs cap rotor & wires are all new I tried swapping coils to no avail. The O2's are maybe a year old but I don't exclude them at all being it's been running so poorly. The FP is set at 35psi with vac off. It has 19# inj. with a matching 75mm pro-m (yes it is mass-air).

Please help you folks are my last hope!

Mike
