I have 48K on auto X...mine shutters at idle mostly when cold. Does not hesitate at all through rest of RPM band. Dealer could not find issue, no codes, so no fix. I cleaned TB and it did nothing. Now I just have a whistle at 2000 RPM, need to change TB gasket I think. I will check my plugs tomorrow and post if there were changes. Also, I get gas all over the place, never ethanol. If anyone has a solid fix PLEASE let me know...this is ridiculous.

Having a shutter when sitting at a red light.
It’s not all the time. I changed fuel source. Changed plugs and wires. Changed coil pack. I upkeep oil changes. Just had rebuilt engine installed. Transmission rebuilt. 144k miles on jeep odo. Was having misfires. No longer an issue. Fuel at fill up almost pops and explodes out of gas tank neck. Seems to have lost power. Not sure where else to start. Any ideas would be greatly appreciated.

Regarding the lost power, that could be a lot of things -- even the trans (presuming it's an automatic). A can of injector cleaner won't hurt anything, and may help. Maybe check the air filter too. I've seen a couple cars where rodents have built a home in the air cleaner box and clogged the filter.
Probably better to start your own thread in the future rather than tag onto one this old.
