Need a Tune-up, or Fuel Injector, or ? ? ?

[GeoDaddy]

My Big Black F250, Full Cab, Longbed... I Have reached a fuzzy point in our relationship. In the last couple of days, it feels kinda sluggish starting up, idling high, sounds like some straining of some mechanical function... until it falls into the next gear. Only variable that I can think of is the A/C which I am using for the 1st time on this 1999 truck with 230,000 miles. It kinda feels like it did last March - just before the Water Pump blew. The only other feeling that I can recall was a couple of years ago when the fellow I bought it from (and I) were driving across country and two Fuel Injectors had to be replaced... but I was too unfamilar with "trucks" to be able to notice any sound... but my friends did. Sounds like a visit to the Ford Dealership for another skinning??? Thanx g

What year? What engine? What code number on the driver's door jam?

The first thing I would do, instead of guessing or taking it to the dealership for a prompt raping, is to borrow a code scanner and pull out the codes out of the EEC. Generally when things go awry, the computer in your truck knows about it, and tries to compensate. It can compensate for a while, then you'll start to feel/see/observe symptoms.

If you don't have access to a code scanner, and have a check engine light (or a volt meter, or a 12V test light), you can wire it up like so at the top of this page, then pull codes doing a Key-on, key-off test.

Hmmm... that's some advice. Let me digest it. It's '99 Ford F250 with the V8 Power Stroke. I'll have to check the bar code on the driver's side door.

No warning lights are on.

I don't have a scanner. Are these available/expensive?

I'll let you know when I get a chance to check out this bar code thingy.

Thanx!

The PowerStrokes have a camshaft position sensor that can really screw with the engine's running quality when they start to go south.
