I dont mind the questions at all ,im glad youre try to help me. The idle will stay at 650 foot on the brake or off in n it will rise maybe to 700 .The problem seems to happen after driving around awhile in local traffic at about 30 the rpms want to stay at 1500 unless i brake and drop below 1000 it will rise to 1500 when i come off the gas . Im sorry if i dont make sense .Thanks for you help Jim

 

I forgot i cleaned tb ,egr maf,,

 

I think that the rpms, with your foot off of the gas and moving, are variable to the speed you are traveling. I agree with pettyfog though, check the PCV and BOTH elbows, you will want to physically pull them off though because cracks will often form on the insode of the elbows.

 

still trying to get a chance to check pcv. jim
