My car is shaking and vibrating consistently during idle. It is a 92ex manual w/ 137k. I had the timing belt done at 84k. I am also only getting 20-21mpg. Any ideas if these problems are related?

thanks.

 

If its a rough idle,

I would:

run some bg44k fuel cleaner through
check spark plugs/wires
dizzy
air filter

If the idle persists then I would lean towards rear motor mount .

Your low MPG could be related to a inefficient fuel system or an o2 sensor going out or clogged cat.

GL abd hope this helps.

 

sould do the fuel pump have anything to do with this?

thanks.
