Everytime I start or come to a stop while driving, the car keeps shaking. I purchased new coil, gave the car a tune up and I am at my wits end.

Need to find out which cylinder is missing.If you can access the injector plugs, unplug them one at a time until there is NO change...that is the one. Do a compression test, if ok, use a meter to check the wire, if ok it is probably the injector. Try cleaning the Idle Air Control Motor.Also clean out around the butterfly in the throttle bore with carb cleaner and a rag.This should help stabilize the idle
