stumbling 03

[huck102800]

My marauder seems to start stumbling after about 20mins of driving normal.I thought it might have been the catalytic converter coming apart inside because that happened to my grand marquis in 05. but it sounds great and there is plenty of air flow. This brings me to the engine. No check engine light the iac valve cuts the car off when i unplug it and the mass air flow sensor changed the way the car runs when i unplugged it so that works also. now i need some of you experts to let me know what you think.

Could be anything, man. I sensed a disturbance in the force while sitting in traffic earlier on my way back from class. No hiccup in the pickup, but a slight tremor two different times while sitting at two different redlights. It wasn't windy, cars weren't going by, so who knows. It's all good, I have to clean everything and change stuff and drain stuff anyway before Louisville.
