My dad changed the timing belt on my 99 CR-V in August and he had some trouble getting it in time (he had to tear down and put it back together 3 times!). Sometime after the timing belt/water pump/spark plug change, I noticed a vibration in the steering wheel while at a stop and a loss of MPG (went from getting 24 mpg to 22.7).
It did not happen immediately after the timing belt change (or at least i dont think it did) so i thought the mpg loss might be due to the changing weather and the vibration coming from a motor mount that i knew was broken, but I got the motor mount fixed and it did not do anything. I think that the vibration has gotten worse, but it seems to be at its worst when the car is really cold. (this morning the temp. was 9 degrees and it vibrated harder than it ever has).
The vibration only happens when the car is in park or at a stop, and it goes away when i accelerate, even if I only accelerate a little bit. I have not noticed a loss in power, or any sluggishness in acceleration. I have tried to research this, and I read something about the drive belt being out of time, but I’m not savvy with cars so I just don’t know.
What could be the cause, do I HAVE to get it fixed, and what do you think a reasonable cost to repair is? Thanks in advance for taking the time to respond!!
