2003 Mustang mach 1 rev issue
Long story short, I had the gas pump in my pony replaced not long ago (they said they put in a Bosch) but she didnt run right at all. I went ahead and put in Motorcraft spark plugs and now she idles better than ever, and if i rev the motor up at a fairly regular speed, no problems at all, however if i punch it real quick, she all but dies.
heres the only ideas that I have:
1) pump cant send enough gas fast enough, not sure what model number the pump is, going back to the shop tomorrow to ask.
2) plug gap is wrong. I think it should be close, but I had a fairly cheap gap tool and could have gotten it a bit off
3) plugs are not torqued properly. I have not had my torque wrench calibrated in a while, so it may be off by a few pounds. its one of the old style ones, not the click type.
4) IAC is dirty? seems to be the solution everybody jumps to when ponys dont run quite right.
Would love some input on where i need to be looking!
