hello all, im fairly new to all this 300zx talk, ive had my tt auto import for about 6 months now 60,000 klm on clock and amaculate in grey. ive had gtirs in the past then made the jump to 300's wow i love it and i can't really see me ever selling!
anyway enough of the life story, everythings been great until i started to notice a slight drop in revs about a month ago. since then ive had a s/s powerflow with japcans fitted, i fitted k+n panel filters, now it seems to be getting worse and when you sit at the back of the car the drivers side exhaust seems to be (farting) and the passenger side is real deep and smooth, ive cleaned the throttle bodies (black) and re-adjusted idle after 300 miles, all my conectors are like new, but the car is still on same original plugs?, ive reset ecu, and checked for fault codes? ive checked everything on the site!!! ive checked the coil packs electrical conectors and pulled them of one by one, the car seemed to misfire differently than does when ive explained.
ive been running it on 98 unleaded tryed it on shell optimax seemed to make problem worse, still does it with air con on?
i appologise for the bible length description,
THANK YOU ALL FOR ANY HELP..........JIM
