Rough running engine at idle
I have a 88 f250 and i replaced the dist. cap, rotor, spark plugs, spark plug wires, and the throttle position sensor and now when i put it in drive and let it idle while holding the brake it seems the engine has created a miss some how. Any idea?

What type of throttle position sensor is it- adjustable or non-adjusting? See this page for the difference- Ford Fuel Injection » Throttle Position Sensor (TPS)
If it's adjustable, you may have not installed it correctly. Even if it's non-adjustable, it could be installed wrong. You need to make sure there is spring tension on the sensor when installing.

I thought of that too, and I could swear there is a diagram somewhere that shows us how our plug wires are supposed to be routed to avoid cross fire but I couldn't find it.
