Don,
A faulty temp sensor will definitely cause the truck to run rich. YOu might want to swap yours with another snesor, clean the plugs and try again. If you don't have access to another sensor let me know and I can send up one to see if it will help.
Cheers,
Paul

I was having cold start issues on mine last year. Turned out to be the heaters on the O2 sensors.

oh yea thanks for the offer paul becouse nobody around had a sensor...lol you would have been getting a call from me

[Paul Grant]

No problem. I'm glad you got it sorted out. I was talking with Kevin when I was reading your post and we both thought that the temp sensor could be causing it to run too rich. Anyway, if you ever need an oddball part like a sensor just to troubleshoot let me know and if I have what you need I can always get it to you quickly.
