Greetings all. My RX300 started for lack of better words jerking while idling and in gear including reverse. It goes away when it's in park and it drives fine with no apparent issues. It has 174,000 miles and I've done the regular transmission maintenance, oil and filter every 25,000 miles, on it since I've owned it. It had 100,000 when I bought it. Any suggestions on what might be causing this issue would greatly be appreciated.

Thanks

Please expand on 'jerking'. The clarification that I am requesting is ... poor idling -> engine vibration (tell us what the rpm meter shows).

The other jerk would be stuttering .. stop and go movement at low speed.

And is the CEL working and or CEL lit/flashing?

Well I believe it might be an ignition coil. It started running rough on my way home from work check engine light started flashing with the codes P300, P302 and P304. Now it won’t start. What a great way to end the day. At least I made it home. 😂
