Well the car is a 1994 honda accord 2.2L automatic. It has around 157k miles on it. About a month and a half ago, the check engine light would come on. I shut the car off and turn it back on and it would go away.

Well it gradually got worse over the course of about 3 weeks. Now when i turn the car on the car starts, idles for a couple seconds, then starts to shake a little then stops shaking. then the check engine light comes on. then while im driving it shakes really hard when the a/c is turned on but when i turn it off, it doesnt shake as bad. what all do you think the problem could be? Battery is new, as well as spark plugs

 

take it to an auto zone and read the codes. possibly an injector going bad? bad plug? bad wire? fuel pump starting to take a dump

 

if its shaking sounds like you might have a bad wire somewhere and broken engine mount.

 

It's a 94,autozone can only scan 97s and up

 

I had a problem similar to this once. I had a hairline crack in a spark plug. When it was cold, the crack wouldn't let the plug spark properly. When it warmed up, the crack in the plug closed and it ran perfect. It drove me nuts. Is the problem coming from a specific cylinder? I would pull a plug wire off when it is acting up to see if you can pinpoint the cylinder. If you can narrow it down, check the basics. Sometimes it is easier to find a spark jumping at night in a dark area with no lights. Good luck.
