limited throttle/bog
I have a 93 f150 4x4 flare side, 302 EFI w/ headers, 5-speed. Problems are starts great when cold, but when warm i have to floor her to start. I have no throttle past 1/4, she just bogs down and sometime pops and bangs along. check light comes on and i lost all but around 1/8 of a throttle and more pops and bangs. new sensors: IAT, EGR, Water Temp, EGR Valve, basically everything on top has been changed. when the light comes on I usually shut her off and turn her back on and she comes back to life till half throttle and then 2 mins later back to a 1/4 and down from there... I am getting a decent amount of blow-by into my air filter box, but i've never had that give me an issue like this one. My gas mileage is spot on and doing great i think. The truck was originally an auto but was converted by previous owner. Does the ecu need to be changed? im stuck on this and im running out of money like everyone else haha... any suggestions? oh and no codes flash when tested....
