Ok i have a little problem and really not sure what the cause of it could be but heres the scenario.

i start the car up and it runs and sounds perfect, but when i get about 5 miles down the road and its in nuetral the car sounds cammed just a very loopy idle. the vaccumn pressure is around 10-12. im thinking its a MAP sensor but i thought it would throw a code. now when i turn off the car and leave it sitting for about 20 mins or more, ill start the car again and it runs perfect.

any help i know you guys are geniuses!!!!

thanks
Sean

im hoping its a map sensor its reading low its at 30.1-35.0 which its supposed to read in the 60's

 

my buddies scanner also says that I'm at 45 % load. someone should know what this could be
