So I seem to be way off track with a few problems my cars been having lately. It started having issues about a week ago. It had a hole in the intake elbow right after my MAF. Fixed that and (just to be sure) bought a new MAF. Ran perfect for about an hour. When I slowed down at a stop light, it stalled. It took about 5 minutes of turning it over before it wanted to start again. I thought maybe my MAF was dirty since i use an oiled K&N filter. I was wrong. I replaced my pre-cat 02 sensors and my Ignition coils since then. Its still stalling when I stop but runs like a champ up until 90 MPH. After 90 it cuts out a little bit on power. My few thoughts now are bad DME, Idle Control Valve, or my VANOS needs fixed. I'm probably not right so any advice and opinions would help me out.

Thanks

Also one thing I forgot to mention is this only happens after my car is at normal running temperature.

Have you scanned for codes yet? There's too many possibilities at the moment to list, you'll have to start narrowing it down more.
