my daughters 97 cavalier has a miss at idle-well actually it just idles VERY rough.the only code it has is multiple misfire.it now has new plugs,wires and injectors.Ive done a compression check and all the cylinders are within spec-no blown head gasket.im thinking its the coil packs.as these are on the back of the motor, what is the best way to get to them to change them?any help would be appreciated.also is there something im overlooking that could cause the idling problem?every one iv spoke to about this car says its the coil packs,so any advice on how to change them would be appreciated.btw this car has 150k miles and has the factory coil packs/module.-thanks,Ted

my 97 2.4 has the same problems,the code said multiple misfire how many are there.the guy told me 4.
