Tj Shaking at idle

I have a 2005 TJ and it has developed a wicked shake at idle, I have done some work to it in the last week and I will list all below. this shake has developed either as a result of this work or is a new fun problem all together. Perhaps someone can shed some light?


Trans fluid change
transfer fluid change
sparkplug change to NGK v
Tranny mount.
new nutserts on skid plate
banks monster full exhaust .( from flowmaster)

I was thinking perhaps the engine mounts?

If you still have the stock engine mounts my question is did you use a poly trans mount? That will cause vibs

I had a little bit of a shake at idle. More of a rough idle. Wasn't sure what it was until a couple of weeks later my fuel pump went out.

It is a rubber transmission mount. but it started right after I replaced the mount. I was thinking the combo of new tranny mount and old motor mounts might be the cause.

I had a shake at idle once, it also had codes though, it ended up being a misfire, i had a fouled out spark plug. If it started immediately after u changed something i would assume it is because of that.

I have no codes I checked yesterday . I figured a misfire but if it was a misfire it would have shown up . thanks for the thought

No it goes away as soon as you touch the throttle. runs smooth with normal power and acceleration

My 05 had a significant shake at idle before I cleaned the carbon out of the throttle body- there is a great DIY here somewhere. Worth a shot before fixing problems you may not have...
