[QUOTE="rich5150, post: 10285142, member: 33227"] The car is a 1993 Cobra, 64k miles Near STOCK configuration -no smog pump FRPP shorty headers/MAC Prochamber/Cat-back exhaust. I just recently got the car, replaced the plugs with stock plugs, replaced the rotor/cap, new fuel filter, new oil, new air filter....etc. The car has ran great with no issues for about a single-tank of gas after all the work was done to get the car road-worthy again. I just took it out for a quick spin yesterday, and the [COLOR="Red"]car seems to break up/hesitate around 4500-5k[/COLOR], only under WOT. If I'm @ 90% throttle or lower...etc smooth as a button as it redlines @5500ish. The only thing that I've done was add some SeaFoam to the gas during this time, which should be all gone now from the tank.... just to remove carbon buildup...etc. Any ideas thoughts as to what could cause the car to do this? I'm guessing it can only be a fuel or spark issue? [/QUOTE]
