I replaced the O2 sensor last fall when the light came on so I have been hoping that that isn't the culprit.

I got the same suggestion over on Planetisuzoo as well as checking the plugs and wires, which I had over looked because I had them been replaced right after I got it in the fall of 07.

I just got plugs and wires today, got them replaced this evening, the shop that I had do the "tune up" after I bought the truck failed to put dielectric grease on the plug ends boots. There was a lot of burns and scorch makes on the spark plugs and the wire ends.

There were a few other things that have become problems that the shop I took it to was supposed to have checked... I now remember why I like to do my own work, it gets done right!

I will update tomorrow after I take her for a drive.
