[QUOTE="03' White Snake, post: 16892055, member: 51916"] What’s the power wire for? Amp? Pumps? BAP? Definitely has a smaller pulley. If the car has a BAP, that could be the issue. Need to look how it is wired. Pre-FPDM or post FPDM. KB directions say to wire post but most cars do exactly what your describing, mine did it too. Changed wiring method and issue went away. Pull the computer in passenger floor area, look if it has a piggy back chip on it. If it does, good news is you can remove it and switch to a SCT X3/4. If not, you might need to have the computer flash at ford if the previous owner did not give you the handheld. The computer is basically locked. These cars are getting old. Could be the fuel pump socks deteriorating in the tank and clogging the pumps. Seen this happening a few times recently. Check the maf connector is good, no damage to the wires. Check the MAF is facing the correct direction. Should have an arrow on it. [/QUOTE]
