I know there are a bunch of threads on this (I have even posted before about a warm start issue)....but now I have a cold start problem AS WELL. I crank the car and it fires immediately - just like always, but it will stall out immediately if I don't juice the pedal some. I have had this same issue as a warm start problem for a while now - haven't been able to figure out much. I have changed out the O2 sensor - several years ago now, new OVP, tried adjusting the mixture, coil, plugs and wires (all within the past 2 years now - maybe 15-20K miles ago).

And I'm getting crappy mileage - never do much better than 14 mpg, which is down from 18-24 - mixed driving conditions. Also have a real hesitation upon initial acceleration...and once I get past that it lurches forward and runs much better at highway speeds.

Any advice would be appreciated.

Thanks, ryan
