Engine stalls/cuts out when cold

[porschaus]

I am currently having an issue where for the first few minutes of driving before everything is warm when I slow down at an intersection and put the clutch in the revs drops to zero and car stalls .

This has only just happened upon getting it back from the mechanic who fix the rough idle due to spacers corroded on the manifold.

They adjusted some settings on the DME to match australian specifications as it was an uk import

So is the issue DME, ICV, head temp sensor or something else

What year is your car? Since it didn't do this before, look for something SIMPLE. If it's a late 80's carrara make sure the three vertical connectors on the left side of the engine are connected. Also check all connectors and hoses are attached.

The only settings on the DME are a rotary switch that can richen or lean the engine, or increase/decrease ignition timing. Normally this switch is set to zero (no adjustment) by turning it fully counterclockwise.

ICV should keep the idle up. you cant try cleaning it. i dont know if a bad CHT sender would cause this. make sure it is connected

also, unplug the battery for a little while, let the DME relearn its settings. you may of had an air leak.

my question is why would a mechanic let it out of his shop doing this???

Carrera DME is not capable of relearning anything since early DME's did not have volatile memory to lose, so disconnecting the battery would be of no use.

You need to take it back and have it adjusted again.
