Hi, Fummins! Thanks for the detailed response.
No yellow cars that I can recall and I skipped breakfast
The car vibrates a LOT in drive/reverse at idle. It's very bothersome when sitting at a stoplight. AC can be on or off, doesn't matter. The vibration immediately goes away if I put the car in neutral.
The clunk/jolt is felt when accelerating from a stop/low speed. I have read it's normal for the trans to shift into neutral when coming to a stop. I'm sure the trans is doing what it's supposed to but assume worn mounts are exasperating the shift.
I know these cars are very affordable and simple and recognize they will feel more spartan and unrefined because of it. However, I do feel I'm dealing with worn mounts. What do you think? I recall that a newer mirage I've driven did not do these things.
If I am to replace mounts, do newer cars have different part numbers for the upgraded 2017+ mounts? Which of the three mounts would make the most dramatic improvement?
The previous owner provided meticulous maintenance records; they indicate the mounts are original. Visual inspection shows cracking. I figure with 100k+ miles they're due for an update, especially since the forum indicates newer model year mounts make a vast improvement. Is this correct?
Thanks for the info on the engine flooding. I'll chalk up the no-start issue to this!
Thanks for your help!
