Stev, actually it was not as bad as I exspected. It must have been cleaned by someone else before (or replaced). And you are right the hardest part was removing the "dog house".

How do you remove the Doghouse? I have an elk conversion and I removed the outer plastic molded piece. I also found the two clamps that are near the driver and passenger's feet. Are there more clamps somewhere or am I not pulling hard enough? The top seems loose but the bottom seems like it wants to pivot rather than pull out toward the rear.
Stev recommends at least every spring since the winter driving causes the engines to run richer than in the summer.
Ok cool. I just started my truck after cleaning it and WOW! Made a huge difference. Not only does it start easier, but before it would start and rev up to about 2000 RPM and then it would slowly come down.. Not the case now. Awesome.
You might want to disconnect your battery for 10 minutes to clear out the memory in the PCM. Once the memory is wiped, over the next couple of days the PCM will relearn how to better control the engine with the now clean IAC valve.
