Default miss in idle

my 2003 turbo has bad shake when in gear both reverse & drive it is running sittng in the garage put from nutral to drive bad shake but it stops when taken out of gear i don't feel anything my seat is now smooth drop in down to drive bad shake .
.only code 0440 probably cap if i put in new cap it throws a 410 an did
this will not cause a bad iddle when in drive what are some of the things to check

ok i found that plugs and wiring might be the answer will update if this is it

ok shake now after new plugs well i can tell there is little shake not much in the that i can feel
but the shake in the air cond. it is bad the shake at idle in gear

Yeah, if the plugs and wires don't help that much, take a look at your motor mounts.

i just replaced the pcv valve so i know it not that
i sprayed the every thing related to air trying to find a drop in engine idle

it all goes backed to the plugs maybe that what the girl was using but what im thinking is re14mcc5 plugs maybe going back to what the mfg. sajested that will be the next thing you mention the motor mounts i replaced both whe non the passenger side i tried to tighten the motor mounts i know there is three

Was the upper and lower motor mounts adjusted per the factory manual? If not let us know and we can post some information on how to adjust the mounts.

Every time I see a post on rough idle I need to read it. I too have it, lots of nice folks on here with professional skills have tried to help. I too have done the spray trick around the plenum to block area. But no help. PCV changed, etc, new plugs, wires, no coil yet although it has a new one when the exhaust valve cooked. I have no codes. Mine smooths out above idle but I suffer from a what a mechanic friend told me he thinks might be a lean condition as I do get some light pinging. One thing he mentioned which I have failed to check as its winter here in New England and last thing I want to do is work on a car outside. Anyway, he advised to check the injector o rings! Hmmm, never thought those could be leaking, or a crack in the plenum some place, arghhh I hope not.

Roadmap, part of YOUR miss is most likely the crappy Bosch plugs you have in it. Mopar uses Champion plugs for a reason. Their engines perform better with them! Get rid of the Bosch and get the proper Champion copper core plugs for your PT. Change them every 30,000 miles. I don't know the proper # for the ones you need, but someone here will if your local parts store can't tell you.

Using acetone is a bad idea. When are you going to give us approved data that says this is a safe method on the PT Cruisers?

Acetone is known to deteriorate cheap plastics and other substances. While the components in a car's fuel system should be of high quality, and thus immune to any deleterious effects from exposure to acetone, be aware that "ideal" is not always the case in practice. Be advised that not all systems have been tested against acetone. Until such thorough testing has been accomplished and certified by an accredited authority, you assume your own liability for experimentally testing acetone in your particular system.

As I said before I would suggest not giving out this advice anymore.

We use acetone at work to melt plastic together.
