Thanks for all of the help and pointers, guys.
Tom, I will be pulling the plenum this weekend to clean all of the charcoal out of the evap hose and valve. I'll measure the injector resistance then.
I have been looking on the svc mnl and can't find any values for checking the coils. Is there a secret place to locate those?
This will be my first plenum pull but from what I have read around here it's really not all that bad. It will be interesting to see all of that stuff down in there. I'll keep you posted.
Thanks again for the help,
