I found a 1990 300zx with manual trans and 59k. Interior is good, but body has dings and bottom of front bumper is broken off but there. It looks like it may have been damaged and repaired right front as front hood gap narrows and paint has a different texture. Bumper is yellow plastic. is that original material/color? Plastic looks aged like it was outside. Supposedly came from Texas. Would need some body work and a repaint to make right. BUT:
The real problem is that upon starting it, it sounds like one or 2 cylinders are not firing at all. The owner jockeys cars, and I think he is trying to dump this one. He bought it this way. I suspect he knows it's not a simple problem as he has been through an auto tech course. Claims he put Seafoam through it and it helped. Also says it smoothes out when you drive it. I didn't drive it as I didn't believe him. There are no unusual noises. Could it just be injectors or electronics? Exhausts are both burning black. Clutch is solid.
Is this a common problem? Anyone have any ideas what the problem is? He just put $600 worth of new BFG tires on it. Any idea what this car would be worth considering it's problems? Could be a money pit.

I have a 1992 300ZX, the tail lights stay on all the time even when the car is off. I have checked all the fuses and changed all the bulbs. Does anybody know the solution to this?

Sounds like magic. Mabe it's haunted. See a priest and have it exorcised.
Is it tail lights or brake lights? Are the front parking lights on? Do the tail lights get brighter when you apply the brake? If no, maybe it is the brake light switch.

Its just the tail lights. The brake lights dont come on when you press the brake pedal and the the front parking lights arent on.

Hey all! I just purchased a used 1986 300zx turbo 5spd. It runs great but always on the second startup. The first time I start it, especially in the mornings, it idles rough and stalls. Runs fine on second start after giving it a lil gas. It even does it when the engine is warm and has been running at running temp. Say I go to the store. In there for 5-10 min. I come out and start the car, it sputters and dies. I start it up again and give a little gas and presto! I'm just trying to figure out what could cause this. Any suggestions?? Thanks in advance! -Matt
