Thanks i will try both of this. I had already scan it and only codes it shows were for O2 sensors

 

2001 Ranger with 155k,

A/C is messed up. Takes a while for the compressor to kick on, and no clue what the source of the problem is. Not the R134a, because I recharged it, and my local garage couldn't figure it out either (at least, not for under $150 to poke around the engine).

Coil pack has gone out on me twice now, once at 112k six years ago and again at 145k last year.

 

I keep losing the right front locking hub. Replaced the bearing hub assembly thinking that was the issue. Put another locking hub on and lost it 2 months later. Any ideas would be helpful.
