After replacing LIM gaskets and putting everything back together my gas pedal now vibrates throughout most of the RPM range and Im not sure what it is. Ive checked the throttle cables and all seems well and the TB or anything else related to intake is definitely not dirty because I cleaned them really really good. I dont think it has anything to do with my new spark plugs which I put in before I started this job and it was running great before. Idle is the same as before at about 1k rpm and everything else is great. Oh and the heater/AC is also off too because I am aware that its normal for it to vibrate when its on. I hope its nothing serious but Id like for it to go away.

I can feel mine vibrate considerably more when the car is cold for some reason, but once it warms up its better. Sorry I can't help you, just thought I'd say that.

Actually that might be what it was because when I left my house for the test drive it wasnt at operating temps and was still low when I got back.

Try turning your A/C off if it'* on....my vibrating pedal is because of the A/C compressor.
