Need Some Help With My 85 Gt

Jun 28, 2013
Hello 5.0 guys and gals. I'm new to the forum and new to the mustang. I bought a 1985 GT with 94,000 on it. it's all stock exept for the rear gears (373) and a B&M shifter for the AOD trans.
I bought the car from a 65 yr old man who had the car for 21 years. Great car and my favorite car as a teenage kid growing up.

The problem the car has is. periodically the car stumbles and runs rough at part throttle. When this happens it feels as if the car is flooding it's self. I can floor the car and it kicks the trans down a gear and runs like normal. It will also idle normal. Then as soon as i take off again it stumbles at part throttle.

The fix is to switch the ign key off, then back on (while driving) and problem solved. It might do it again the next time i drive it, or not again the next 5 times i drive it.

No check eng light comes on. The car has a new tune up with car,rotor,wires. Has new fuel pump,pick up and sock, has new ign key. All done right before i bought it.

Any suggestion would be greatly appreciated.

My car drove to work great this morning and to lunch and back.

My car does not have sun frame connectors in it. I was considering them to help keep the car nice and tight. Which brand are you guys useing ?
Sounds like a carburetor issue. On sub frames, Stifflers makes a great set, along with their interconnecting FIT system and Spider braces. Global West is another top flight brand, along with Maximum Motorsports and Kenny Brown. BBK and UPR are another couple choices out there. Sub frames are one of the best mods you can do to your car to improve handling.
As long as they are a nice sturdy unit you will be fine, make sure you get weld in ones.most of them are just a 1x2 rectangular tube bent to fit, I bought a se of upr connectors. They were fine.
