156 misfire problems
Discussion
Just bought a 1998 156 2.0 TS as a non-runner and have spent the weekend fiddling - it now goes like the clappers on the open road - I love it!
However, it won't idle properly, and stalls when I dip the clutch. Idle speed hunts between 200 / 2000 rpm when cold, and settles down to 300 /500 when hot. Revs don't pick up at all when it's cold.
I've been told it may be the air flow sensor but I'd like another opinion before I fork out 150 squids on one. Or maybe an AR dealer can diagnose it? (and the diagnosis would cost £150?).
Any help appreciated. I'm itching to get the car going. More fun than a barrel of monkeys as they say in the song !

Thanks to everyone for their advice. In the end, it was the throttle servo motor suffering from friction and stiction. Cleaning it out with WD-40 and checking and de-griming all the linkages cured the problem (almost). The engine speed still hunts slightly, but it doesn't stall.
The car still occasionally does something of a 'kangaroo' job at low speed in low gears. This may be the same cause as the unstable idling, so I'll have another go at cleaning and lubricating everything.
Thank you all again.
