Not a question. A hard-won answer.
If you have just recently tuned your Altima, replaced the plugs, coil, distributor, etc, and it will turn over, but not "catch", your problem may be the timing. Mine was just a little off, and the vehicle would start, stay running until it warmed up, and then promptly lose spark. I spent a great deal of time looking for bad wiring (there was some, and I replaced it), a bad fuel pump, dirty fuel filter, and just about everything I could think of. It turned out to be a combination of the timing and a very sensitive oxygen sensor. If the timing is off just enough, it will cause the oxygen sensor to shut off the engine. Depending on the vehicle model, your altitude, and a multitude of other factors, the timing should be set pretty close to 20° BTDC. Just a little off and your Altima may die unexpectedly.
have the same problem?
