I cleaned my 03 GMC Envoy's throtle body, after which I removed the 2 PCM fuses in the fuse box for 1 hour, then put them back in the fuse box. Now I can't get my Envoy to crack nor the remote keyless entry to lock doors. The door locks won't lock. What can I do to get these problems to go away short of taking it to the dealer? Thanks. Scott

Your stuck, the dealer is the only one that can reflash the system to bring it back online. The same thing will happen if you don't use the special tool when you replace the battery. Why would you think you needed to reset the computer when you clean d the throttle body? These systems are smart, they can detect stuff like that and reset the idles speeds as needed. If you have the owners manual read it, there is a lot of information in there about your vehicle, so this kind of thing won't happen to you again.
