My car will drive ok and then start missing and sputtering sometimes and when I give it gas it feels like their is no power. If I slow down or stop it will sometimes die altogether, but will restart. No check engine light. Have had it put on computer twice and nothing comes up. It is like it is not getting fuel or the pipes are not letting the exhaust out, but they said my pipes were ok. When it sputters I can smell gas. How do you check to see if your check engine light is faulty? thank you.

1997 Nissan Altima Question: My car will drive fine and then start missing and sputtering

Vehicle Application: 1994 Nissan Altima GLE 2.4L 1996 Nissan Altima XE 2.4L
1995 Nissan Altima GLE 2.4L 1997 Nissan Altima GLE 2.4L
1996 Nissan Altima GLE 2.4L 1997 Nissan Altima XE 2.4L
Customer Concern: The engine will not start, it will crank like it's out of time. The spark plugs get wet with fuel.
Tests/Procedures: 1. Check for oil inside the distributor on the crank angle sensor disc. Clean oil out of the distributor with an electronic contact cleaner, if necessary. Also check the Positive Crankcase Ventilation (PCV) system for being plugged up, as the possible cause of oil getting inside the distributor.
2. If the distributor is dry inside, it could still be defective, so scope the distributor and check for 0-5 volt square wave signals on the Yellow (Y) and Blue (L) wires. The Y wire should have a clean consistent 0-5 volt square wave signal every 1 degree of crankshaft rotation. The L wire should have a clean consistent 0-5 volt square wave signal every 180 degrees of crankshaft rotation with three narrow signals and one wide signal, with the wide signal denoting cylinder number 1.
3. Verify battery voltage supply to the distributor on the Orange wire.
4. Verify ground for the distributor on the Black wire.

It sound like you got some water in your fuel or a bad fuel filter
