Recently bought a 91 Accord. Very nice except it shakes when at a stop even when warmed up (actually more when warmed up) especially w AC. A guy with a 93 accord told me to let it be. Should I increase the idle manually or just let it shake? Thanks

 

What's it idling at?

 

motor mounts might be bad. the car is a 91 after all.

 

my aunts 92 camry shook like a ****, but ran like a champ...its prolly just old age...i suggest motor mounts like others said

 

Idle should be at 750 when warmed up with or without A/C on. if it isn't get it there and then check your motor mounts. They are rubber insert type and will deteriorate with age.

 

i had the same issue, mine was because it needed a bad valve adjustment, it was way out of spec.

but the mounts are also a more common cause of this, mostly the rear
