engine idles wierd
First time posting. I have a '94 F-150 4x4 302. When i start it, it idles way down almost choking off. Then it will idle way up and back down again until almost choking. It will do this a few times until either cutting off or staying idled up really high. I've tried new plugs, wires, dist. cap, fuel filter, MAF, pcv valve. Even thought it might be a vacuum leak but can't find one. Any help on this matter would be much appreciated.

anything to help a fellow ford truck man, also if you can spray the intake with FI cleaner with the engine running about 3-4 times a year to help prevent this in the future. (since you have a MAF sensor follow the direction on the can) I do not recomend using Carb clearner, make sure it is FI/Carb, stright carb will eat at protective coating i've been told.
Good luck.
