redemption

i fixed alot of my problems as i cleaned my act and bought a new tps and a new FPR vacuum hose, but when i am WOT the car will misfire for a second and continue on, ive narrowed it down to just a little bit now it used to do it alot, i just cant think if i getting enought spark or my fpr is just blow out?

if it misfires under load I'd check tune up parts like cap rotor wires and plugs but I'm sure you may have already replaced these so it could be a bad coil....but without having an ociliscope hooked up when it's under load it'll be a little more difficult to narrow down a cylinder on which it is misfiring or if it's a random misfire which would point to a component like a cap or rotor or coil
