Car Forum / Nissan / Nissan Cars / July 2005intermittant stuttering
my 94 pathfinder has a problem where sometimes when i start it, and drive off, it will stutter and run poorly, its hard to explain, on accelleration it sputters and sounds like its missing a cylinder or two, when coasting its fine, this doesnt happen all the time, just once in awhile, ive done a full tune up with oem parts , any clues? > my 94 pathfinder has a problem where sometimes when i start it, and drive > off, it will stutter and run poorly, its hard to explain, on accelleration > it sputters and sounds like its missing a cylinder or two, when coasting its > fine, this doesnt happen all the time, just once in awhile, ive done a full > tune up with oem parts , any clues?

Fuel pump weakness then failure are not uncommon on nissan quest vans, I replaced one on '95 quest with 120K mi a few years ago. Pump noise was a high pitch wine, which I thought was nominal. May want to have the problem looked at or it may leave you stranded. My died right after tank fillup at station. just had the same problem,called out mobile tuner.not very good news,needs new throttle body. £400,from nissan,£100,on ebay, if its the throttle body at fault,m and the problem is only intermittant, then isnt there some individual part at fault on the throttle body like a position sensor or that screen thingy inside or something instead of buying the whole throttle body? it just doesnt seem that my throttle body is at fault to me > my 94 pathfinder has a problem where sometimes when i start it, and drive > off, it will stutter and run poorly, its hard to explain, on accelleration > it sputters and sounds like its missing a cylinder or two, when coasting its > fine, this doesnt happen all the time, just once in awhile, ive done a full > tune up with oem parts , any clues? go out and wiggle the connector at the air flow meter let me know what happens > my 94 pathfinder has a problem where sometimes when i start it, and drive > off, it will stutter and run poorly, its hard to explain, on accelleration > it sputters and sounds like its missing a cylinder or two, when coasting its > fine, this doesnt happen all the time, just once in awhile, ive done a full > tune up with oem parts , any clues? starts normal > go out and wiggle the connector at the air flow meter > [quoted text clipped - 6 lines] > full > > tune up with oem parts , any clues? if wigglin it was sposed to make it start normal, then i guess next time it starts and runs funny, il try turning it off and wigglin the wire and connector > go out and wiggle the connector at the air flow meter > [quoted text clipped - 6 lines] > full > > tune up with oem parts , any clues? |
