As I write this I am in a state of exhaustion...had no help today, so tried to push car across yard into shop and gave up, so did the work in the open sun. Got the new belt and tensioner in by mid day and started car up. Ran good, started normally, just with a high idle. Drove it into the shop and found the vac line from the MAP sensor had come undone at some point. Decided to set/check the timing, and found it at about 16-plus at idle, in park, with CTS unplugged. Plugged in the vac line to the MAP and set timing at 12 degrees. Shut it off and started putting tools away. Decided to drive it around the neighborhood, and car would not start.
Eventually got it started by opening the throttle. Checked codes and got 13 and 13, both MAP related. Swapped out the MAP for a known good one, no change. Also unplugged MAP vac line while running, and it would barely idle. This leads me to believe the MAP is good.
I found a couple of small, rigid type vac lines leading to the purge canister that were unplugged near the throttle body as well. Just before I quit for the day, I was able to get two normal starts out of it, but then it idled rough. Found fouled spark plugs, which also have a good bit of wear on them. Will replace them in the a.m. with a new set of RN12YC's and see what happens.
Sorry for the length of this post, but I am also worried about leaky cam and crank seals. Saw lots of oil and grime when changing the timing belt. I don't have the special tool needed to replace these.
