Hey everyone, I'm new to this forum stuff, but you guys seem to know what you're talking about!! I have an 88 Mustang 5.0, 5 speed. Stock motor with pulleys and exhaust. The car is a conversion from 4 banger (not done by me .. what a mess!!) It has recently started sputtering and missing under light load. Wide open throttle it runs like a champ, but normal driving is getting frustrating. I've done a general tune up as the car recently sat for a better part of a year. Any other suggestions?! I've searched through a bunch of other threads and people have talked about checking the fuel pressure, should I try this?!? Any help would be appreciated!!
