Woke up this morning and went outside, started the car and it died. It ran for like half a second. Turned the key again, it did the same thing. I could keep the idle with my foot on the gas, and it would rev, but it would just die unless I was on the gas. After toying with the throttle and driving it around the block, I got it to idle (barely) at 400rpms.

I figured I got some water in the gas, so I limped it to AutoZone and got some stuff to take the water out, and since I had just under a half tank and it only treated 10 gallons, I got 2$ worth of gas and then limped it to work (20 miles). When I pulled into the parking lot here at work and put it in neutral and took my foot off the gas, it died again. When I drove it, there was seemingly no loss in power at all.

Any idea what it could be? Stock 97 4.6 GT with a K&N Air filter (w/ silencer removed) and welded in Flowmasters. That's it! Thanks for all your help guys!

No CEL ? Did you recently re-oil your K&N ??


Try disconnecting your battery for 10 - 15 mins and reconnect, see if that helps.

K&N was re-oiled about 6000 miles ago, at the same time the fuel filter was changed. No check engine light.

I'll try cleaning the IAC later tonite. Thanks!

I would replace the IAC and or check to make sure there is no oil from the K&N filter on the Mass air meter sensor. Most likely a bad IAC motor though.
