starting to hate my z.

havent ran injector cleaner since beginning of this year, and havent changed spark plugs yet just kinda waiting for it to be not so cold and being a little lazy.

I'd start by addressing those 2 issues first since it's cheap and easy (especially injector cleaner). I know they say plugs are good for 100k but IMO that's BS; I change mine every 50. A set of NGK iridiums will run you about $120 and take about 2-3 hours to install if you take your time. You have to remove some plastic covers, the strut tower brace, and the upper intake plenum. Then you need to have the correct socket (it's small). It's an unnecessarily complicated PITA compared to the Mustangs I'm used to, but it sure beats paying the dealer to do it.
