Shakey

[wlmrt6]

ok so i got some motegi rims and some nexen tries on my 05 gtp. and i noticed the car shakes going around 40 to bout 60mph. so i went back to the place that did my rims and they re balanced them and everythign was fine. now i notice that if my car is cold and i rev it just a little when the rpms come back down it shakes a little. then when i was idling i felt like someone was pushing on my car shaking it. but then after i drove around alot there was no shaking at idle. what the hells goin on????

Vacuum leak?
Bad/dirty MAF sensor?
Time for a tune-up?

I'd lean more toward a vacuum leak, though. Welcome to the forums, BTW. You may consider doing an intro thread in the "Introductions" section.

no clue what youre talking about. we need more symptoms with hard data from scanning.

well a tune up shouldn't be the problem just got new plugs last fall and i usually run a lucas injector cleaner every other month. i haven't checked the MAF sensor. well i already said the problems there dude. It shakes at idle its not a rough shaking just like if the it were really windy and you felt it moving. also shakes going down the road between 45 and 55 mph usually when i accelerate then let off it shakes.

worn out suspension components possibly. how many miles?

82,000 miles

does the car idle funny itself (jump rpm)? does it make any funny noises? does it sway more during certain conditions? does it do this with the stock wheels?

I'm kind of having a problem like that with my 95, runs smooth and normal around town but get it over 60 on the highway and keep the same RPM for very long and it shakes, let off the gas and it stops shaking, replaced the throttle position sensor and it still does it, any ideas?

i really just notice it on idle. the rpm seem to stay still. no funny noises really.
