Question about 1984 Nissan 300ZX

2 Answers

1984 Nissan 300zx,

The car idles just great! It sounds fantastic! However, whenever I give it gas the car revs up then goes back to the idle while I'm still on the gas, like its choking it's self. It does this repeatedly the whole time I am on the gas. We changed a bunch of hoses and tubes... what can cause this??

Having the same problem myself at the moment, if you are sure that it not a vacumn leak somewhere, check your fuel pressure regulator (replace if bad), then check your EGR valve, your PCV valve, and then your throttle position sensor. If the car had been sitting for a while, it will more than likely be one of the above is stuck. Hope this helps.

Have ticking sound when idling goes away when given gas. Checked oil it's okay think it's a stuck lifter if so how can this be fixed it's on 95 Nissan pathfinder

I had lifter tick in my 300zx and added Rislone engine treatment. Worked great. Give that a try. Make sure your oil is clean. Might be worth doing an oil change then adding the Rislone, per the directions. See if that helps before doing any more serious work.
