DAng girl you have had nothing but problems with that car! Well as stated before an easy way to check for misfires is to pull each plug wire at the boot with the engine running and listen for the idle to change.If it changes then that cylinder is the getting some spark to it. Make sure you wear some good insulated gloves to protect your hands in cause a wire archs over so you dont get shocked. Now if your engine idle doesnt change but your can see that your getting spark at the wire, the next thing is to check your injectors.Loosen each clip at the injector connector and again with the engine running, pull the plug out andlisten for any changes in the idle. your rpms should drop a bit telling you that injector is working. Hope this helps!
