drives fine for a while then starts to sputter and sometimes dies. it acts like it is not getting fuel. changed air filter, fuel filter, fuel pump. Did not help at all. even if you rev it the rpms do not move when it is acting up. now it is starting to smell like something is burning and the heater will start to blow cold air. can't afford to keep guessing. need help

    Sounds like it can be one of a few things. If your engine light is on go and have autozone check it. If its running lean you have an air leak. If it sputters and stalls it sounds like it can be a timing chain slip or issue. In that case you need a new engine (repairs for dual overhead cam runs upwards of 1000-1500.) If your getting random misfire codes it is most likely the timing chain.

    If its not getting power it could very well be a lower intake manifold leak near the gaskets. which run about 300 bucks to do.

    I would honestly pay to take it to a shop have it inspected and thrown on a machine. that way youll not only know the issue but youll know anything else thats wrong

    I'll take what's behind answer #1. Have the coolant level checked .If you have someone rev it up , does the exhaust have a 'hissing' sound to it , like a mass transit bus? AND do the vacuum gauge thingy! And then to prove it , loosen the down-pipe just enough to let it breath a little and see if it runs better. Good luck.//////NEVER MIND....just noticed the date on the original post ....Duh.
