Okay while driving there is no surge or idle problems except when coming to a stop I take it out of gear and it will surge a bit but when coming to a dead stop, the rpm's drop low 400rpm maybe less at times and the lights dim then surge to about 8 900rpm and couple times then smooth out to about 600. But if I step on the gas rev it up a bit outta gear before the stop it does'nt surge.

Thanks for any help

 

bump any new ppl with this problem ? any help very appreciated Thanks

 

It sounds like the IAC to me. It looks like you said you replaced it, but they can very much be bad new. I went through 3 new ones in 2 weeks before I got one that worked.

If thats not it, it could be either a vacuum leak or a bad MAP... they both lead to the same symptoms.
