Hey guys,

I bought this 1988 gt mustang, and its non mass air, and the guy put a 480 lift cam in it. Then you gently press on the gas it reves fine.. but when you rev it fastly it hesitates and coughs... what could be the cause of this? Please Help

I'd pull the codes off the EEC first, but if I have to guess I'll say either an ignition problem (coil, plugs, wires <-- most likely), or a fuel pump going out.
