around 1200 to 2000 rpm my truck is missing. it is a 5 speed and has 40k. anyone else have these issues? what can i do to correct the problem. i am new to the forum and any suggestions would be appreciated. thanks!

 

Hi and welcome to FTE! Glad to have you here.

Might be a little early with only 40 K miles, but first thing I'd try is new plug wires. But, being an '05, it could be pushing 3 years old and that seems about normal life.
Seems plugs and wires are two of the more common causes of an engine "miss".
That is unless it is a dead miss; like one cylinder not firing every time. But, if that was the case you'd likely get an OBD-II code and the Check Engine light would come on.

If you do decide to replace the wires, I suggest Motorcraft. (You can find them cheaper than from the dealer.)

Again, welcome and keep us posted.

 

ok...drove my truck to work today. now the engine light has come on. havent replaced the plug wires yet. how do i check to see what the code is?

 

You have to have access to an OBD II code reader.
(OnBoard Diagnostics - 2nd generation)
Try AutoZone or a local shop. Autozone will generally do it free of charge.

Come back with your code info and we'll try and help.

(I guess it's reasonable to expect a code indicating a miss on cylinder "X")

edit to add: It would not be unreasonable to at least check to make sure all the plug wires are secure at both ends: on the plugs good and tight, and secure in their coil pack sockets on the other end. You might get lucky!

 

hey. had it checkout at the dealer and they put a new coil and plugs in it. seems to be running well now. thanks for the help!
