idle issue need help asap

[johnny5]

ok guys i need help asap, my car well, im ready to junk it. i jsut replaced my plugs and wires, cap and rotor dont need to be replaced for another couple thousand miles, heres the deal, it shakes like its not firing a a cyl. found cyl 1 dumping fuel, replaced the injector and now the car wont stay started. it seems to want to idle at about 500 but it just cant, any thoughts? its not me and my friend stumped and wer both certified, we just dont know a lot about nissans.

Are all four getting fuel and spark?

[johnny5]

yes sir they are, im thinking i need to adjust the idle screw, but anyone know how to do that when you have abs and you cant get a screw driver in there? and it seems i cant get enough down pressure if i use a socket with a screw driver head

Check for vacuum leaks. That would cause a rough idle. Are the spark plugs gapped properly? Fuel filter clogged? Cat clogged?

[nismoracingsx]

get an offset screwdriver..might help.

Sound like dizzy timing to me. I would try and time it and see what it does. Are you throwing and codes?

If you junk it can use it for a project.

ok wellll my crank doesnt have timing marks, that i can see, the plugs are brand new AND gapped properly, all vacuum lines are hook and BRAND NEW, fuel filter is new, cat cant be clogged as i have 7, some hack up hair balls but for the one on my car, well its a test pipe sooooo, anyway i think its timing/ idle screw issue, my friend denies it soo i guess ill have to play a lil and see

[dsastr_clan]

something like that happened to me when i replaced the injectors, i didnt know it but it was the oring on the injectors, i got them brand new from the nissan dealership but i gues when i put them back i cracked one and they were leaking, also becareful when u install the rail back if u tight one side first then the other they wont seat right neither

check that your injector is getting a signal with a Noid light, should flash when car is running.

OK I see, so you're a certified mechanic and you haven't tested the fuel pressure regulator, did not see the obvious timing marks on the block around the crank pulley, did not try a new air flow meter and didn't check the vacuum hoses for leaks or missing clamps?



I guess they let just about anyone get certified these days... or perhaps there is less to you then you let on.

The problems can be the idle speed setting, stuck choke or fuel flow obstruction.

hey ***hole, ive had my crank pully off, theres no marks on it i clean and looked for them when i had it off so i can paint them and make them stand out, but nope no marks, as for the hoses and clamps, i you read youd see i already replaced everything that has to do with that so i know its not that, and the maf i already went through, try to read a lil before flaming, and be glad your not around me for a cooment like you made, i worked my a** off to get certified, i just dont know nissans,
