Hello All:

It has been the day from hell-- this AM in -15C weather, my wife called from the side of the road-- the '92 945 had overheated!

Turns out the neck snapped off the radiator (the usual top inlet). I need the car on the road, so for $300CDN I picked up a rad locally and installed it.

The current problem, which predated the rad woes, is that the car will stall on deceleration, particularly if I step quickly off the gas. It only happens under load (in gear). Sometimes the check engine light flickers, but it never sets codes (1-1-1 on sockets 2 & 6). Wiggling the harness for the RPM sensor does nothing.

The throttle body is clean with a new gasket, all the vacuum lines have been replaced recently, the idle air valve is clean and seems to be functioning correctly.

Any ideas?
