Guest Anonymous Posted January 10, 2003 Share Posted January 10, 2003 Hey guys, this is a list of the problems i'm currently having w/ my stock 76 280z. Car gets shitty gas milage. It smells rich at idle. Idle jumps around, 800-1300 RPM. 3 times i have been driving hard and when shifting at 5000 RPM the car has completely cut out and will not start for 5 min. There is a strange lope in the engine at idle and an odd pulse in the exhaust. Guy i know says it is a vacuum leak. I just replaced air filter, fuel filter, new afm, system diagnostic, new plugs, did timing+wires. So what could be causing this? It's kinda embarrasing when you're racing a prelude with your girlfriend in the car and the car up and dies when you shift into second! Also, the mpg is just throwing money away. So, vacuum leak? given problems, where is it likely to be? or what else? fuel pump, injectors? it starts and drives like a champ normaly, plenty of power.

Guest Anonymous Posted January 12, 2003 Share Posted January 12, 2003 bump LOL, you guys, i always chime in on people's problem's where my knowledge is applicable. This aint no Znewbie who thinks muffler bearings need replacing every 10000 miles. This is a serious problem that ive been struggling to fix for a while. This is my daily driver, yo! im still in school and i need transportation and my only ride is busted and no one here knows how to fix it. Anybody who can chime in?

denny411 Posted January 12, 2003 Share Posted January 12, 2003 Check for a vacume leak at the fuel pressure regulator. I had the same problem with my stock 77. I changed all the vacume lines and the problem went away. The vacume line to my regulator was hard, and cracked on the bottom where you couldn`t see it. This caused a vacume leak, and also kept the regulator from doing it`s job. Quote Link to comment Share on other sites More sharing options...
fl327 Posted January 13, 2003 Share Posted January 13, 2003 Hey guys, this is a list of the problems i'm currently having w/ my stock 76 280z. Car gets shitty gas milage. (((((((((check voltage at the o2, running without one wont cause the stalling, but you will run rich))))))))) It smells rich at idle. ((((((((clean head temp sensor connection))) ((((((((check to see what condition plugs are in)))02 sensor Idle jumps around, 800-1300 RPM. (((((((check out the ignition module, also check to see if cap and rotor are secured , also check the distributor to see that it is not loose)))))) ((((((grounds, check them all, also check fusible links to see whether or not one is corroded)))))) 3 times i have been driving hard and when shifting at 5000 RPM the car has completely cut out and will not start for 5 min. ((((((tps, check for continuity, clean connectors, look at the links, check out the efi fusible links especially, whats going on with your radio when this happens, if it continues to play, your efi fusible link is not to blame, i had a car that had a corroded link at the efi and when it would go out the radio would go out but all lights would function, which mandated i keep bumpin and repping the west coast)))))))))))) There is a strange lope in the engine at idle and an odd pulse in the exhaust. Guy i know says it is a vacuum leak. ((((((((very well could be, but i cant see it stopping you when you are driving, check all vacum especially for cracks by the afm or possibly a loose clamp.)))))))))))))) I just replaced air filter, fuel filter, new afm, system diagnostic, new plugs, did timing+wires. So what could be causing this? It's kinda embarrasing when you're racing a prelude with your girlfriend in the car and the car up and dies when you shift into second! Also, the mpg is just throwing money away. So, vacuum leak? given problems, where is it likely to be? or what else? fuel pump, injectors? it starts and drives like a champ normaly, plenty of power (((((((injector test, disconnect each one at idle one by one, if at any of them idle does not change, you either have a faulty injector, drop resistor, or bad connection to the injector driver on the ecu, fuel pump issues are usually constant, but you could check the voltage that it is putting out, may be a shaky body ground))))) a bad injector would give you a hesitation, and most likely it would not stall at load, just run crappily))))))))))))))))))))))))))))))) off the subject, have you checked out my buddy shane's new hip hop clothing store that just opened a short while ago in davis, ask him abaout the tall chinese guy that had a red 240z with a v8 four speed in it, he will give you a discount.
