OK, want to figure out what my problem is. Been going on for a few weeks, and finally a weekend to troubleshoot, and figure out what the hell is causing it.
I have a vibration at idle and anywhere else. Hard to explain.. but its a vibration enough to loosen screws in the engine bay. everything has to be tight, or it will wiggle loose. When the car is running, if I hold the throttle open just a little (2000-2500rpm'ish) and just hold it there (by throttle rotor), I can feel the engine vibrating like its coughing or misfiring (if it did it any less, you wouldnt be able to notice). It will hold whatever rev's you want it to, but you can tell its not as healthy as it once was. Im going to do a compression check tomorrow, any other things that I could test/rule out?
When driving, if accelerating slightly hard, the vibrations will get worse as you are coming up on 3k rpm... just for maybe 50rpm, not all the time though.
The vibration isnt a huge vibration... its that vibration that is just enough to annoy you since it finds anything that is loose in your car and will make it rattle.
any ideas? maintenance wise, all is pretty good. plug wires checked out ok, plugs are slightly white on the tip/metal arch part, and have some black sootish stuff around the base, but nothing extreme.
not burning any oil or using a bunch of gas, or oil leaks.. just a freakin annoying vibration.
compression test results are
250, 250, 248, 250.. good there
any ideas?
also took off the balancer belt just to eliminate a somehow bent shaft.. no help there.
the vibration does not stop when clutch is engaged.. so its not the clutch.
motor mounts, doubt it since i had a front insert before, and the engine never had this "shake" to it.
