1997 Tracer- ruff idle / Stalling. 3 cylinder misfire.

Question

I have a 1997 Mercury Tracer that has a problem anytime the car is stopped the car run very ruff, the car shakes in a "Bucking" manner, then will shut off, the Oil pressure light and the check eng, light come on, the "E" brake light is on at all times (and is not engaged)

Today I got the car tested with a computer thing at auto zone, it said cylinder 3 is misfiring.

The car doesn't shake or buck when in Neutral (well not nearly as bad but a little bit)

PLEASE HELP I CANT AFFORD A NEW Car, and would like to keep repairs cheep.

Answer 1

spark plug is the most common thing  next the plug wire  than a coil

also add a little fluid to your brake fluid
