Check your fuel delivery, and your spark.

[sk8punk235]

Check MAF, clean it too.

ya turn key but don't start just for power and listen for your fuel pump...

[ShereKhan]

yup i had a similar problem and i replaced my fuel pump, fuel filter, and starter only cause it was going bad and my car starts like a champ again

[heartofaskyline]

ya turn key but don't start just for power and listen for your fuel pump...

i bet its a fuel pump

[1989240sx]

so what type of sound should i be hearing when finding out if the fuel pump is working

[LovesBigTurbos]

umm not sure how to explain in like an electornic motor starting for 2 seconds(give or take). sound should be coming from fuel tank. correct me if I'm wrong.

[rob912]

even better have someone turn the key while you stand at the rear of the car. the sound should be pretty noticable though

[LovesBigTurbos]

^^^ that could work too

[1989240sx]

so i started my car today and it actually started and stay alive on it own is this usually if the fuel pump was bad also it sound like it is miss firing too

[steeda763]

I had the same symptoms several times.

Check to see if your plugs are fouling with oil. If they're not dry and white/tan in color, you should replace them. It's also a good idea to replace the spark plug wires and distributor cap if it's been a while, or you have no idea when they were replaced.

Fuel filter is a possibility. Fuel pumps usually die completely...they won't go in and out (unless you're having another electrical issue).

If it's missing, I almost guarantee it's the three items that I listed in the ignition. Luckily, they're all reasonably inexpensive to try out.

[1989240sx]

plug wires have been replace but the other stuff you listed it has been awhile so i am going to start with that and go from there

[1989240sx]

so i have not fix my problem what i notice is it does not what to idle around 750 rpm it has been idle around 500 rpm so my question is there something that controls that ??

[Gr8plainsDrifter]

fuel filter or iacv

[notslow]

Ya I would start with the easy stuff. Cory240 (i think his user name is) has a thread on how to clean out your IACV (not that it is some huge project ha ha). Do the fuel filter too.

[1989240sx]

ok so i final got the time to clean my iacv good thing i was doing my fuel filter a lot easier with the fuel line out of the way so i will let you guys know how it runs

[1989240sx]

i also have other problem me car is leaking oil form the valve cover one of my bolt holes are strip does anyone know of a thread repair kit to fix it . i know that they are out there my i have not clue what size i need

[1989240sx]

ok guys so i fix my valve cover from leaking oil . now back to what the true problem at hand it car does not what to stay alive i clean iacv and i put on my fuel filter change my plugs , cap and rotor so what else can i do

[1989240sx]

i did some searching and i found that i can clean my throttle body that could help with idle too i should go to auto part store and see if i am got and codes coming up i will let you guys know what happens

[2ndnissan]

There is an idle set screw on the sohc 2.4...It's on the front of the throttle body..as you look toward the back of the car it's on the right front corner of the t-body. It looks like a nut with a bolt coming up through it..very small. The bolt part has a slit in the top of it. It's kind of between the spring for the tb and edge of the tbody cover. Anyway..you hold the nut part with a wrench and turn the screw with a small standard screwdriver.You loosen up the nut...turn the screw...then tighten the nut up again when you have it set like you want it.

[1989240sx]

i will have to give that a try

[1989240sx]

ok i think it is getting better here is the thing when i start the car up the rpm start about normal then it go down and almost want to die what would be causing that
