hey guys my 91 240sx revs good and all but when im driving at say a constant 40 the car hestitates or stutters. but it will do it atanyspeed really then it will kick out of the stuttering which is only for like a second, and drive smooth and have power. if it stutters and i give it gas it kicks out of the stuttering. i just bought the car a little while ago so i dont know when the last tune-up was. you think its just plugs, wires, cap and rotor? thanks for any help.

clean ur maf... spray a healthy dosing of choke cleaner all over the sensor inside it

agree^

cool ill try that the car does have 165,xxx so its prolly dirty. i will also chang plugs and all that crap just for maintence reasons.

change your fuel filter/air filter while you at it

yeah i have a new intake on but ill do the fuel to wheres it located?

By the Starter Kinda...you will see it. most of them are gold or sliver color.

And put some 93 oct. gas in there too.

yeah stp injector cleaner and 93 always goes in, just have to go get some. Thanks, ill get a new fuel filter in it.

Fuel filter?

That would be located on the left strut tower, you'll see hoses connected to it.

might not even apply to you, but i had similar stuttering problems with my 93 as well. I cleaned the maf and changed the fuel filter with no results. I ended up replacing the O2 sensor and that fixed the problem right away. if those listed above doesn't help, try checking that... won't hurt to replace them either at ~160,000 miles
