So my truck is a 2002 V8 5.4L Ford Lariat F150 Truck with about 150,000 miles, it used to be supercharged before we had this problem, but we had to sell the supercharger for the labor the mechanic put into trying to find this seemingly unsolvable problem. The air to gas ratio has seems to be the biggest issue, the truck struggles to get up to speed and during its struggle the truck spits gas causing an unwanted surge forward until it gets to about 40 MPH and is all around shaky. Recently the catalytic converters burnt out so we sawed them off and ran straight pipes while reconnecting the co2 sensors to the new pipes. We have checked the coil packs, replaced the fuel filter and pump three times, and checked all the fuses, vacuums, and any wiring we can reach... I would hate to let this thing go, it would just break my heart... any suggestions or answers would be appreciated, Thanks!
