Dear Art Benstein,

Hope you're well. When last I worked on this car - a few weeks ago - I neglected fully to re-seat the Throttle Positing Switch (TPS) wiring harness connector. I found this error today, when I went to disconnect the TPS, as you suggested, to see if that would help matters. Once I seated the connector on the TPS, the idle stabilized at a tad higher than normal (perhaps 800 revs/minute (RPM) versus 700 RPM. I'll adjust this, on a day when temps are higher.

Thanks again for sharing your analytical insights, without which I'd still be at square one!

Yours faithfully,

Spook
