i have a 96 fwb it misses at idle and when I try to step on it a little it hesitates and takes a while to get up to speed it didn't start till after my opti went out changed it and a couple days later it started missing bad and check engine light started flashing so changed the plugs and wires, tps, fuel filter, fuel pump was changed like a year ago..... my mechanic told me to get the icm checked since all accrued after opti failed said it could have killed it also......any other thoughts, thanks
