So I am on vacation and my 450 started missing. As far as I can tell it misses when it is in drive as apposed to neutral. My milage is still over 15 mpg and there is no MIL. I am thinking it is a vacuum line or modulator but I am not sure. Also sorry if someome has already posted on this but it was kinda hard to do a search on my blackberry.

Check your fresh air hose that goes to top of the engine. (on the left to the PCV hose)
Crack maybe on the inside (towards the back of the firewall) you may want to remove the hose for inspection.

Well I made it home but the engine is missing something terrible. It seems to run ok when the RPM's are above 2500. Does anyone else have any other ideas?
I remember beowulf said somethimg about the fuel pump relay has something to do if rpms above 2500 and engine runs ok, its located near the wiper washer solenoid valve-right side if you're facing the car. these can be inspected and cleaned as well just to be sure youre not changing the wrong part
