I just did the plugs and changed the oil in the car... b/c I just bought it... I gapped the plugs at 45... It was fine yesterday but then today started sputtering.. if you rev it while its in neutral ... it sputters like its missing a little.. but the idle is fine...?? plugs??? control module???? what could cause this...

oh yeah its an 88 gt 5.0 w/intake h pipe w/no cats and dual flows

It sounds as if you might have sprung a vaccum leak or your EGR is acting up.

Pull the plugs and make sure one is not broken, or has the porcelin cracked.

See if you can isolate the missing cylinder by putting a timing light on each plug wire.

My guess is that the stress from changing the plugs killed one of the wires, and when it needs to carry heavy spark current, it fails.

i would yank the codes and see what gives. also run the cylinder balance test while doing so. if the balance test reveals nothing, carefully (do at your own risk) pull one plug wire at a time to see if you can isolate the bad cylinder.

good luck.
