Engine Mechanical problem
1993 Nissan Altima 4 cyl Front Wheel Drive Automatic 150K miles

The car starts, but idles rough and stalls after about 15 seconds and I'm not getting a check engine light. I've replaced the fuel pump, filter, and pressure regulator, but none have worked so far. Also, I have checked all of the vacuum lines and they seem to be in good condition. Do you have any other ideas as to what the problem could be?

When was the last tune-up?

Check the IACV/AAC valve, Throttle position sensor, PCV and EGR valves-also for an exhaust restriction

I've only had it for about 9 months and the dealer told me that they did a tune-up on it. I don't know how in-depth it was though. Also, I've noticed that it cranks better and seems to run longer after it's been sitting for a little while. After I crank it a few times, it doesn't want to start again.

Make sue battery is up to fully charge

Okay do below and determine if its is fuel or spark

Get a starting fluid or ether and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

You need an EGR Valve about $100.00 at Auto Zone and easy to install. If that didn't help you can do the whole tune up yourself and it is easy. Get a new Air filter, spark plugs, spark plugs wires, and the distro cap, change the oil and oil filter cap. You may not need it but the new O2 Sensor helps. If you do all of this it will help pass emissions and help the idling. The cost maybe around $250-$300, Mine altogether cost $250 doing it myself and it run like new now and it pass emissions with flying colors. If you have anymore Question my e-mail is PNBreza@hotmail.
