Thank you Mr. Bowtie!

When I had the IAC out, I had no idea it disassembled, let alone moved for all the crud. Next time in, I'll see what I can do there. I may have bumped the MAP Sensor connection, last time in, but I wasn't in that area. I'll check that one. Would a suddenly clean throttle body change air pressure enough for the code?

I have to check the radiator fluid quite a bit in the hot weather due to the intake manifold leak (how can GM get away with that one?) until I can change the gasket - it stalled for the first time on me today (idling at a light) and it was the first time I've seen the temp gauge over the mid point. Took a quart and a half to get the fluid to the hot line and a while to cool down.

Any pointers on cleaning the intake manifold - since the throttle body was caked, I imagine it's pretty thick in there, too. By the 2nd picture, can the intake manifold be removed at that level of assembly, or will I need all the clearance I can get in an Astro?

Thanks again for the illustrations. You could put a better manual together than Chilton or Hayes combined with those graphics.
