94 corolla rattle idle problem

[rmiller]

My 94 corolla shakes and rattles at idle even when it is warm. Any ideas of adjustments to fix this problem. It seems to run fine at higher speeds.

Is it a caburetor type engine?

My old '94 started doing that right around 60,000 miles... I threw in a new set of plugs and wires, tossed on a new accesory and timing belt and had the tranny fluid swapped...This seems to have helped a bit...You may also want to have the injectors cleaned at a dealer, because those bottles of FI cleaner only do just so good.....

my '99 will be getting the same treatment here shortly....that is except for this one has a timing chain, so I don't need to swap it out yet...

The best way to get rid of it is to do a full tune up and check all the engine mounts to see if any are worn out.

i had this problem on my 4a-fe.... i started to fix it by tightening the throttle cable... it helped... would have helped even more if i had known there was an actual throttle body adjustment screw... there's a plastic cap on it.. pull the cap off (dime sized) and adjust it until the motor stops surging....
