Spray around the throttle shaft with wd40 ,if the idle changes you may have a worn throttle bushing causing a vacum leak.

 

ive driven another 30 miles and all is well, in fact i just came from starting and letting it idle and still it is acting right, i will check the linkage, can i do it the same as i check for vacum leaks using propane? AND THANS TO EVERYONE HELPING,

 

thanks a million everyone , i have no clue but its doing great now , maybe it was just moisture from when i did the cooling flush
