2000 RPM Issue
OK, once again I need HELP!!! I read my computer and I have no code that says it's the MAF however, i did test it and it works geat as per the test. So I decided to purchase another Computer and it reads the same, No problem except code 31 which I have the Air disconected (85 300zx 2+2), The car starts great but I can not get it pass 2000 RPM.
Question? Could it be a vacum hose? or what can be disconnected to get by pass the problem so I can have a better idea were to start. The car is in great condition, totally redone, but does me no good tojust have it parked.
SHold I take it to Nissan and bend over, or can a mechanic resolve the issue.
Like I said I have the Manual and all seems well. PLEASE HELP!!!!!!!!!!

I have to agree with ZBum it's like was said. I've had this problem in the past even though it wasn't throwing an error code. See if you can get ahold of a new or at least known working MAF. Do you know anyone else who owns a Z31? If so maybe you could borrow their MAF just to see if it works.

resolved RPM issue,it seems that I found in the harness a bridged wire from the iddle control that was cut at the ECU. and went on back to the rear passenger pannel... A box by the spare tire. anyways this wa done and I have no reasson why the old owner did it. as soon as I cut the bridge going to tha back the car iddled back to normal. I connectect it and once agin could not get pass 2000 rpm.
Anyways, the ECU should not have had that wire bridged. So everything is fine now. Thanks everyone for your suggestion
