Thread: Putting or sputter?

Been having this issue for a month or two gradually getting a little bit worse. The car runs great otherwise. Just putts at idle or really low rpm. Thought this was because I had oil in the #2 spark plug tube. Changed the valve cover and cleaned it out so its not leaking any more. As well as did a tune up: plugs, wires, rotor, cap and seal all OEM parts. What else could it be? bad injector, clogged up cat? Any guesses? Thanks.

no one has a guess? I can get more video if thats the problem. Its gets worse it seems after the car has been driven around.

Change the fuel filter? After 20 years,no telling what kind of funk could be floating around in there.

it was swapped last year for the 300zx one. I wouldn't think it would be bad yet but its a possibility. Is there any way to tell if a PCV is bad? Not that I think its my problem but I think it might be a problem.

nevermind just looked and saw how cheap they are so I'll pick one up. would a clogged up cat do this?

Nope.

Clogged cat eill either rattle or your exhaust will be way quiet and you'll be down on power. My guess is vacuum leak

sounds like a bad injector to me.. i had a similar problem before on my n/a b13.. switched out the injector and problem solved..

ser.net has a wealth of info on tune-up and troubleshooting. Do you still have the stock EGR system?

I have some different injectors on the way and already have new rings for them, as soon as they get here I'm swapping those. EGR was removed by previous owner. I believe I do have a vacuum leak but what is a easy way of tracking it down I've checked what I could easily see?
