Stumbling, bit of hesitation... help
Hey guys,
My 95 SC400 just got out of the body shop today (had a big dent pulled out) and on the way home it ran a bit rough and was stumbling. It was definately down on power. It feels like it's only running on 7 cylinders (still moves, just a noticeable power loss). When I romp on the gas it'll still go through the RPM range fine, and no black smoke comes out off the exhaust (I thought it could be ignition related).
Is this a common issue with these cars? I don't really want to take it in to Lexus if I can avoid it I cleaned the throttle body today without any significant results.
Any help is appreciated, thanks.

Could be bad gas or maybe one of your plugs is fouled or possible a plug wire has a crack in it and is arching to nearby metal (check for this at night - if you have a crack you'll see it spark). Just a few things to check. Also you can isolate the problem by removing one plug wire at a time with engine running - pull one wire and see if it effects the engine - if it does - plug it back in and check the next one. Eventually you'll pull a wire and you won't notice any effect - thats the bad wire or plug. Worth a shot.
