Question about 2006 GMC Envoy
1 thing to check before you go replacing the PCM. We have plastic intake manifolds which are right below the PCM where your heat lamp was. With temperature related problems similar to this, I'd check the manifold bolts for tightness (these have a tendency to become loose causing vacuum problems). Easiest to check are #5 & #6 near the firewall. When the engine warms up, the plastic will expand causing no problems, but when it's cold, will contract and have vacuum leaks. Do you have any check engine lights? pcmforless.com is a good sight for repairing PCM problems if you deem this is indeed the problem. You can send your PCM in and they even send you a loaner PCM while yours is being repaired, but they have several programs to choose from.
