Hello I had a bad miss and stumble , and anything over 1/4 throttle would buck and backfire.. I have since replaced TFI module, TPS sensor,IAC sensor, new plugs and wires, new fuel filter and new fuel pump... Now the stumble and buck are gone , but still have ever so slight miss ... Also replaced the cap and rotor too... I am glad I can floor it now, without bucking ... just wish I coud eliminate this darn miss.. I have also checked my vaccum lines..

i would check the ignition timing make sure its set where it needs to be....it could also be the ignition coil staring to get a little weak.
