Help this car is driving me nuts!!! It drives fine when it's cold and cold outside. As soon as warm weather comes it will drive ok for awhile and then it begins to buck and then it will stall out and will not restart until an hour or so later. I've replaced the fuel filter and it worked ok for a little while, then went right back to her old ways again. I live in southeastern Ma and have taken it to a variety of machenics, they all say they don't know what it is. They canged the oil and replaced the serpintine belt. The check engine light stays on for the majority of the time. I called AutoZone and explained the problem to them and they said it was the crankshaft positioning sensor ?? What is that and where is that? I'm ready to throw in the towel and sell it, could anyone PLEASE help me.

MsDebba welcome to NICO!

Stalling and bucking can occur due to a wide variety of problems. When the check engine light comes on, its usually indicative of the O2 oxygen sensor. There are two on the J30.

This is my advice either read the ECU or have someone who'e familiar with Nissans or the 300zx engine read it.

You can do it yourself. The instructions are on this thread:

Its fairly easy to do. All you need is some patience and a small screwdriver.

She's not overheating when she stalls she just keeps cranking until she's flooded or battery dies from trying so much. Then it's a waiting game till she'll start again. When she starts to buck I'll put it in netrual and give her gas until I can pull over to a safe spot. I was wondering about the spark plugs. the parts are so expensive for this car. I just called autozone and coil wires are 136.00 ea. thats crazy!! She rides beautiful except for this one problem. Thank you for any ideas you or anyone else can give me!

Its not a good idea to flood the engine on this car (its a high performance Nissan design), you'll invite more problems.

As for parts try these guys:

OEM Nissan parts not autozone knock offs at a fair price.

Use only Nissan OEM sparkplugs, anything else and you WILL have problems gauranteed.

Your car is an Infiniti and not a Chevrolet. The reality is you'll have to "pay to play".
