I replaced the spark plugs, thinking that was the cause of the poor performance I was getting.
The car still idles rough, the steering wheel still vibrates...is my car on its way out?

 

sounds like maybe your motor mounts are going.. that would cause it to vibrate..

a dying tranny would slip between gears or shift very hard..

 

clean throttle body..

 

Thanks! Argh...I should have kept this car stock.

 

ok when i drive 75 on my wheel shakes..? i dont know y .. i never had my spark plugs changed EVER! there still OEM. if i change them what plugs should i use for the best performance? i have my timing advaced .. i did it by eye will these plugs cost me a arm and leg?? o yea i have a VG!!! lol

 

get your wheels re-balanced, that should help keep the vibration down

use stock (ngk) plugs when you get new ones.

 

not too smart.....but I guess as long as you don't advance it too much, still not too smart!

 

its all good....

 

I replaced the plugs, cleaned the filter, and still the car is weak below 2500rpm. Still no fix.

When I cruise @ 70mph, it feels as if there slight bucking sensation. Also, there is "resistance" from the gas pedal.

Help!

 

I did a search for instructions onhow to clean the throttle body...nevermind.
