03 3.0 shake at idel

[rangers92]

my 3.0 has some noticable shake at idel. it also shakes a little more when cold or the a/c is on. i have changed the plugs wires the batery the serp belt the fuel filter i run fuel injector cleaner regularly. an i use 89 gas. the shake calmed down some when i changed the fuel filter. however i am getting great power friom my motor i am getting no missifres no over heating no knock or tick and it revs good. very smoth as well. i have been told all rangers shake specialy the 3.0 something about the resoneces of the unibody and motor?? just looking for insight. also in the summer im rebuliding the motor. all new water pump alt power sterring pump starter and ac compressor. along wiht maybe head gaskets and pistons. motor has 106k on it and starts fine. also while it shakes at idel the rpms stay dead still and constant and only increase a little when the a/c is on. just looking for some insite not worried or anything.

Ever try cleaning the back of your throttle body, intake air control valve, and your maf sensor? It smoothed out my idle nice when I did it.

yep i did all of those i even bought a new idel air vavle but when i pt the new one on it seemed to idel worse i i cleaned the stock one with break cleaner as told ot and put it back on and it smothed out some. clean my tb and maf sensor to. i mean the shake inst bad it could proably just be me being picky becuas i need every thing perfect.

What's your idle rpm? I will say the 3.0 is not a smooth idler, at least to other V6s I have driven. You might also check your engine mounts. Also check for vac leaks especially in the PCV system.

also in the summer im rebuliding the motor. all new water pump alt power sterring pump starter and ac compressor. along wiht maybe head gaskets and pistons. motor has 106k on it and starts fine.

But it's your money.

Does it have the original belt tensioner?

My 03 has the same issue.....ive went as far as to change the plenum gaskets trying to weed vacuum leaks out....still not solution....it drives me nuts!!! it idles like a dang diesel but drives smooth and enjoyable.Ive also had several people tell me for some reason that the 3.0 is a rough idler...i wish it idled like the 3.0 in my escape lol or had the power the escape does DOHC FTW.....

it idles like a dang diesel

Yea, my I4 Camry idles dead smooth, but it has a balance shaft system to even out the lumps. I'm wondering if this is just poor QC and or design in the balance of the crankshaft. I've learned to live with it.
