Hey guys, thanks for yalls help with that LONG list of problems. haha. But i was reading your page rizzspeed, and the hesitation on my Z seems to be exactly like what the article talks about. The article gave a lot of different causes. Another problem with my Z that i failed to mention is that it takes an incredibly long time to start, like 10 seconds
its horrible and embarrasing. Buy anyway, i was wondering if maybe those two things are linked together, and maybe that narrows down the possibilities of the problem? thanks for your input!

 

Try the simple things 1st. Fuel filter, air filters and spark plugs. Changine the oil couldn't hurt either. Won't help solve your problem, but at least you'll know the oil is good.
