I have a n/a 1990 300zx M/T with a vg30de the car starts and runs, but it seems that the 1st and 6th cyliner arnt working i unpluged the coils and it had no affect, i was told its either the ingnition coils or the fuel injectors i know its not the coils i assure you. I did a full tune-up but didnt change the pcv plugs (i Will but is it important?). the car drives very sluggish and when i giggle the fuel injector wire-harness the car sputters also it revs at 2k rpm after i have been driving a while...what should i do first? i hope you have the answer to my question im dieng to get it fixed i hate driving a rice burner i will do anything to get this problem fixxed!!! also i unplugg the tps and nothing happens is this bad?

Hey thanx slowZ but about how much do injectors cost? and where can i get fairly priced ones?
It's about ~$400 to fix. Make sure it's the injector by putting a long handel screw driver on top of the injector and put your ear to the handle. If you hear a loud clicking then your injector is good in not bad.

sadly i do agree with the ingector problem... i hate to say it but you can always look on E-bay. 1990 Z's are prone to injector prblems due to that damn ethonol in gas now... and to fix, they arnt cheep. also, i've had great luck with "Marvels Mystery Oil" fuel injector cleaner/ fuel system treatment. (about 6 bucks). keeps my 1990 NA purrin' like a champ.
