So I got my 91 GT fired up tonight and it's running a little rough. It's idling rough line the plug wires are on wrong but I checked and they aren't. When I try to rev it up it hesitates really bad. What could my issue be? Any help would be greatly appreciated.
Need some help!!??

Well idk, I just got done installing a 255 in tank and a T Rex inline and they seem like they are working correctly. It shows fuel pressure at the regulator as well. When you turn the pumps on it goes up to around 38 lbs. Is that correct?
Mine started hesitating few weeks ago, couldn't figure out what was up. Went on-line and saw most mentioned the MAF and throttle body. I took off MAF and noticed the wires inside were broken !!!! I had put away the original one and replaced my after market one with Original and she started up like a champ. BTW, I gave the trottle body a good once over with trottle body cleaner as well just in case flap was gummed up. Give that a shot.
