You need to have your engine flushed and cleaned out. One or more of your spark plugs aint firing. You need to replace them all to include the wires as well. If you dont get your engine flushed, you could blow your engine up.

the pcv valve is behind the alternator between the alternator and oil filter. when you remove the oil filter you can see the pcv in the intake manifold. best way to get to it is through the pass side fender under the rubber mud flap thats between the wheel and engine.

SOURCE: 1997 nissan pickup 4wd, just had timing chain

Not likely. You have a 4 cyl engine with over head cam. It has hydrolic lifters. If it wasn't making the noise before he replaced the chain, then its something he did...or didn't do. If it was making the noise before, most common reason would be 1 or more lifters not pumping up. If you have a six cyl, no one changed the timing chain, (It doesn't have one!) The 3.0 6cyl has a belt.

SOURCE: 1995 nissan pickup throttle position sensor

ok on a 2.4l on the black/green and white wires use ohm meter and there is no specific spec for that engine just make sure the the resistance changes and there is no dead spots. for the 3.0l black and white wires specs are 1.0-9.0k ohms im guessing the specs are the same either engine. close to full open

I doubt it is anything other than the iac valve or the computer.
You could unplug the iac and see what it does, the throttle cable could be hanging up in the car too.

When I give it gas it acts as if it can't take it. Almost like it needs a tune up.


Try the fuel filter, it's right by the tank above the rear differential. It also could be the idle air control on the throttle body. I don't know these are just guesses.
