I am coming up on 200,000 miles. So far have averaged 28mpg and only had 1 repair for $23. So no complaints. Anyway, now when I decelerate from 65-70 mpg, it decelerates with jerks. Especially noticible when the cruise is on and you go over a hill, and the cruise backs off the throttle. Engine idles smooth. Power is good. Any help would be appreciated. Thanks.

 

may help if you tell us what you're driving, what engine, what trans..

basically anything.

 

2000 Galant, automatic, 4 cylinder.

 

whenever i turn on the AC/heater, the car jerks a little bit. the dealership took a look at it and said everything was fine. i just put in a new battery and ever since it was put in, thats when the jerking started happening. any suggestions? thanks
