i have a 1989 5.0 5speed mustang lx hatchback with 98,000 miles. completely stock other than off road h pipe. The car runs really good during a cold start. Drives great sounds great until it warms up. After driving for 5-10 minutes it looses all power when trying to accelerate, Poping thru intake, bucking real hard, running rich, It gets so bad if you run it awhile you cant go over 30mph, cleaned the I.A.T, replaced, Tps, EGR solenoid, fuel pump/filter, MAF, set timiing and TPS to factory specs. after doing all of that the car runs exactly the same. i was just hoping for some opinions so i dont keep throwing money away for nothing. any help is appriciated, thanks
