Im having problems with my idle, when i come off the highway (or going over 45mph at a constant) to a complete stop my idle is at 1300 to 1400rpm after no more than 5 seconds idle drops down to 600rpm and bounces to 1300rpm for about 6 to 7 seconds. ive been told (by an "expert") than i have a dead spot at 4ohms (not sure what that means) i really appreciate it if i could get some help pictures and DYNO information will be posted soon.

100% stock car? Could have something to do with the FIAV? Have you done any searches?

There are literally thousands of idle problem post out there and about 98% of them lead to the same thing.

Start off by:

Checking the ISC. There is a youtube video on how to check it.
Block off your FIAV to see if that is the issue. There is a plate that blocks off the FIAV and leaves the ISC functional. It's like $20
Check for vacuum leaks.
