Hi there ace,

There are several possible causes

  • Vacuum leak. Check hoses and connections for a hissing sound.
  • The EGR valve may be leaking
  • The PCV valve may be plugged
  • Air filter may be clogged
  • Fuel pump not delivering sufficient quantity
  • Timing chain stretched/Worn timing gears
All are easily checked. You'll need a timing light for the timing chain check. A can of Carb Cleaner for the valves.

Get back to me with what you find out. We can take it from there. Good luck Ace

Starting ruff


I'm leaning toward a bad sensor, as in throttle body temperature, or coolant temperature sensor. The smell of too much fuel is probably from pushing pedal to start, which shouldn't be necessary on a fuel injected vehicle. What does it do if you leave your foot off the gas pedal during start? As far as fuel filter goes, if it hasn't been done in a while, I'd do it anyway just as preventative maintemance if nothing else.
