1. car stalled and once I held the gas pedal down and was able to hold the key over and crank the engine a huge puff of black smoke came out of the car and it seemed to run fine, although the service engine light came on. It eventually went away after a week or so. 2) a week or so later I started the car, it turned over fine but had no power, it simply would not go. It did not even realize I was pushing on the accelerator. 3) I removed the key from the ignition in frustration and then tried again. The second time the car worked fine. It revved when I put my foot on the gas pedal and then took off just fine. 4) this began to be a more common occurrence and if I took the key out or waited a few minutes it would straighten up. 5) not now! the car won't move forward. And now it is even starting to stall out and flood. 6) now the battery even seems to be running down. This has all taken place in the matter of about the past 5 weeks and now it won't move forward or run at all.

We purchased a 2003 Nissan Altima 3.5 on 12/2002. On 7/16/04 the car wouldn't crank until the third try. After starting he wouldn't go but 15 mph. Took to dealer and their diagnosis was the throttle chamber was defective. It has been two weeks now and the part has not come in because their telling me its on back order. Called and talked to several service guys and requested a loaner car until my car got fixed. We don't do that anymore replied all the guys. So I called the GM manager and left a message, he called back and said he would check on a loaner and call me back in the am of 7/30/04 by 9am. He took to long so I called him at 934am went to voice mail.
