REAP_

Okay thanks for the help everyone. I ended up opening up the AFM and seeing if the previous owner had tampered with it at all and of course he had. The AFM was set for a rich fuel mixture. I ended up fixing that and the car is Running better. As for the problem with cylinders 3 and 6 yes the spark plugs do have combustion deposit and raw fuel on them. Also I did put new fuel into the car instead of running what was in there.

zed head did tht car was running and able to be driven, just this morning started with the no response to throttle acceleration, from what i can figure so far the maf is going bad

changed plugs when bought car 3 and 6 are black with raw fuel, believe injectors are stuck open, todays issue that started to happen was when i went to give it gas it would just bog out no response as if it was running out of gas release throttle and it idles fine leining towards M A F issue ?

The engine still runs and yes it is missing. I recently got the car about a week ago so I went in and replaced all of the plugs but as replacing them i noticed that the two were wet. The plugs on it before were extremely worn so I figured that may have been the reason for the misses. After replacing them is when I noticed that three and six were still coming up wet. The car idles fine and drives fine but this morning the issue of when i press the throttle Instead of picking up the RPM's or giving more power it feels like it wants to stall. Im trying to figure out why three and six are coming up wet and also why the the car is losing power when pressing the throttle. I figure that it may be the Air Flow Meter.\

Hey everyone I have a 77' 280z that has two major issues that I am currently aware of. The first is that im getting raw fuel on the spark plugs in cylinders 3 and 6, I'm assuming that those two are companion cylinders. I replaced the plugs, cap, and rodor and still had the same issue. I believe that the fuel injectors are stuck open. Any help with that would be great. As for the second issue I seem to be losing pressure every time I press the throttle down. Honestly when it comes to that issue I have no idea how to even start fixing that. The issue just happened this morning when I turned on the car to go get the flywheel machined. Any help will be greatly appreciated. Also I noticed that once the throttle was losing pressure the exhaust began to backfire.
