Hey guys, just joined this site, hoping I could get some help with my Z. Been having weird problems out of it. It started missing about two weeks ago, thinking it was a coil pack, I switched them out to see if the miss followed and it didn't. So I thought it may have been an injector. When I was in the process of getting the injector my car got worse.when I would try to pull out and accelerate it acted like it didn't want to do anything and just bog down. Idled like shit and used gas like crazy.so I finally got my injector and installed it. It took away the crazy idle and some of the bogging down. But it still misses really bad. I changed the spark plug also and no luck. Does anyone have a suggestion as to what my problem is?? About to pull my hair out please help!!
