Thread: car sputters really bad

alright so my 1998 gtp is sputtering on acceleration and misfiring when decelerating. i have replaced the coil packs and the plugs and wires were done this winter. i just changed the fuel filter just to see if that may cause it but nope. i just did the entire cooling system flush. when i had it scanned it only came up with a bad o2 sensor error code. replaced both knock sensors replaced the o2 sensor.

could it be a maf sensor? mines looking really sketchy but its been that way since i bought the car and this is a recent problem.
any sugestions? plz help im about ready to trash this thing

it could be the maf or the map, have you tried pluging the maf to see if that helps?

if the cat was clogged then there would be all around driveability problems

i havent tried the maf or map yet and there is no cat on my car =]

replaced maf problem is gone now thank you. only reason i didnt do the maf first was because some kid told me maf's rarely go bad and i believed him. thanks again for your help
