My 2005 Altima 2.5s would wouuld not start the other week. The engine turned over and it died immediatley. When trying to start, the starter would hiss, but the engine would not turn over. After several minutes of this it finally started blowing a large cloud of smoke out. This has never happened before. No engine light and the shop did not find any problems. Two days later after driving 250 miles, the idle was high and the SES light came on. Had it checked and it was due to high engine idle speed. We then drive 600 miles home without any issues and several days later the light turned off. The idle speed is sometimes high and sometimes normal. Now I am noticing that when I am dirving and let off the gas, the car will jerk for a second and then be normal again. Any thoughts? Thanks

What color was the "large cloud of smoke?" Also, do you know what code was found when the scanned the engine? Have you checked for vacuum leaks?

Let me know.

Thanks for the response. The cloud of smoke was dark gray. The code found was P0507 I beleive. The definition of it is " idle speed control system RPM higher than expected". I have not had a chance to check for vacumn leaks yet. Thanks for your input.

Brian:

Check for leaks and let me know what you find. I have two other concerns, the idle air control valve and the smoke. White smoke usually indicates coolant getting into the combustion chamber from a bad head gasket. However, if it was light gray, it could have been the same thing.

Let me know and thanks for using 2carpros. Com.
