All: Started this morning to get the BB's few quirks figured out while it's still winter. Last year the car ran great, but it had trouble staying running for the first 5 miles or so. Cold start no problems, let it sit and idle for 5 minutes, ls no problem. Once underway, as soon as I let off the pedal, it would want to stall. I was able to get through it by using the hand brake, but that's a pain.
I know I have a bad vacuum valve that is supposed to shut the throttle body down on decel, but I've just plugged it and left it place. If it's not plugged, the open vacuum takes the idle way too high. It's been like that for two years, but not for long if I can find a new one. The AAR is working but I'm not certain about the Thermotine sender. I'm sure Jeff B or someone smarter than me has the specs to bench test one. If anyone has suggestions on what might be the problem here, I'm open to all suggestions. Cheers! Rob Attached thumbnail(s)

Test your CHT.
It could be failing when fully warm ? |
