Idle is surging all over the place and now occasionally dies. Seems to be about 500 - 1000rpm.

- Air cleaner clean; preheat valve fixed in permanent fresh air

- IAC is clear as cleaned 5K miles ago.

- Cleaned out throttle body last night (made problem worse). Audible click of TPS can be heard.

Attempted to set base idle (via black knob) with IAC hose plugged. Really didn't affect idle.

Other oddities. Car now seems to ping at boost - this is running usual tank of 90 octane 10% ethanol blend. Maybe a bad tank of gas??

More history: Recent T-belt change although it idled OK immediately after. The only strange part of the t-belt job was the cam gear wobbled when I took it off—IE the roll pin was bent over a bit. I did straighten and insert but wondering if previous owner had timing adj to compensate.

Apologies in advance as I realize I'm all over the place here. Need to step back a bit. Any insight appreciated at this point.
