94 magna/ can anyone help? when in Drive,my car vibrates,have tried adjusting idle,no good.can it be the TPS,any one with simmilar probs.

when did you last service your car?

plugs could be dirty and need replacing.

is your revs all over the place? or is it just sitting really low?

hi,last serviced at ultra tune,5 months ago,revs idle 800/drive 600to 700 and vibrates, when i turn on a/con revs pick up but viration still there very annoying ,in R its very smooth.
just bought 7 months ago.

check your engine mounts. when they are broken the car will viberate alot. the common one is the drivers side one. this will be located behind the washer bottle. look for any spilts or cracks or chunks of missing rubber

ok,thanks a lot will check it out, never thought of that.thanks

hi,engine mounts ok

umm then best would be to check the pulgs and plug leads. also if you say your car was serviced 5 months ago id strongly reccomend you service your car.

Ash change your pic sick of that one.
Check your 02 sensor if your plugs and leads have been done recently.
My paj is doing the same thing. So sad and irittating. Reason i suspect 02 on mine i have and air fuel ratio meter installed. Mine is running quite lean for some reason and giving it throttle wouldnt change air fuel mixtures which it used to do fine. Same issue on gas. I think my gas conversion pushed my 02 sensor over the edge lol.. I cant detect any vacume leaks on mine.
