problem with rpm
 

my trck is a xlt 4.2 97,,, my truck in d running good, when i stop the rpm down less 1000 rpm, and gauge of rpm star up and down and she turn off,

Clean your IAC valve with some carb cleaner. It sits on top your throttlebody and is held on by two bolts. Clean it out real good and put it back on and see if that helps.

Ummmm, I'm speechless!

reef, is that keyboard working all the way?

I'd definitely make sure the IAC is clean. I am not too sure if fuel filter could do something like that, but I wouldn't doubt it if it's really gunked up. Try that one too.

How many miles on the truck and what was the last change of plugs, wires, fuel filter, air filter, ect.?

Have you guys ever wondered if Reef might be deaf,or has a speech impediment? How would you like it if the tables were turned!
Anyway,try cleaning the IAC like Peacemaker suggested.If that dont help,try cleaning the MAF sensor.Also,clean the throttle body but with throttle body cleaner only! Good luck and keep us posted! :thumbsup:

All his other posts look good...

Anyhoo, I think you have a lot of things to work with here reef, post back what you find.

Actually his other posts look way worse! Maybe we are being too hard on him, sorry. I shouldn't have replied in the first place, as it wasn't too constructive.

Reef's cool. I think he's from a different country and he doesn't speak English very well. I believe the guy that was typing for him told me that was the case not to long ago. So would you please give him a break, he's just trying to get his problems taken care of the best way he knows how. I have no problems understanding him.

Reef, change your fuel filter too. It may be clogged up. And make sure all your plugs look good and the wires are on tight.

Let me know how it goes. :thumbsup:
