I got one for you.

When it first started doing this it was while it was warming up. Now it does it all the time.

While idling in gear the rpms like to drop to 500 (supossed to be what 650 idle?) and sometime below that. It will start to drop a couple of times. Then just flat out die.

I think its a my Throttle positioning sensor.

Or it could be this. Once upon a time i blew the heater/cooland hose that runs coolant through my throttle body off. So i replaced it and bipassed the throttle body all together.


i have a 1996 f150 XLT 302 (5.0) with 117000 miles.

Let me know,

Thanks,
Anthony

Ps. it isn ta major problem, just curious to what it is.

Knowing if there were any codes might help. I'm a little rusty where gasoline engines are concerned, but I do recall TP sensors being an issue on 5.0s and also intake gasket leaks were quite common too.

definately hook up the hose. Thats how it knows how warm the engine is. We have replaced a lot of isc motors as well. Those are sensitive to vacuum leaks as well.

be careful with the brake fluid, its also a pretty good solvent.

it cant be any worse than the prank pulled on my hood.

I work at BK (make it your way) And my boss decided it would be hilarous to spread mayo on my hood. Well i made him wash it off. It didnt seem to have any residue. Next day went mudding and guess what there wa sa grease mark on it. And there is a now very permanet (since jan) dirt mark on my hood...

And i cant get it all off. a bit comes off everyonce in a blue moon.
