Since the winter is over, and I don't have to warm my car up... I just jump in, fire it up, and go...

But now I have a problem... My motor definitely pulls WAY harder when it's cold, especially from lower RPM's... like from 2,000 rpm in 2nd or 3rd, it pulls like crazy...

But as soon as it warms up to operating temperature, it loses that "SNAP" that it has when I try to accelerate when it's cold or starting to warm up.

AND, I now I have hesitation sometimes, randomly, in any gear at any speed. I put my right foot down and a second or so goes by before anything happens...

Has anyone experienced something like this before? I have 165k on the clock, but she runs great, doesn't burn any oil, etc. I always use 93 octane.

Any help or direction would be great! I finally got a digital camera, so I'll post some pics of my car soon...

Thanks a lot guys!

 

it all in air density...cold air makes for better air/fuel mixture that makes more power...once it gets all hot and bothered ur hot air jsut sucks the power out just like any other car.....but if u have hesitation i sugguest checking ur plugs...clean ur fuel system....clean ur TB......and maybe even a knock sensor

 

+1. right on.
