bad idle with vibrations 850 1994

posted by  someone claiming to be tapsa on  Thu May 4 22:14 CST 2006 [RELATED]

Hi,
for one week I have poor idle conditions, on higher rpm s it runs fine and has power there. One could compare the symphtoms similar as having choke on in old cars.
sofar I've checked: no codes from A2 nor A6, running temperature ok
-all vacum lines going out from the distribution tower are ok, carburrator body is clean with two holes in the bottom open.
-flame trap is clear, spark plugs are in fine condition
-idle air control valve gives small vibrating feeling with power on but is it working correctly? how to check
-regulated gas pressure shows 2.8 bars and is regulating fine
-checked most electrical connectors accessible around
my plans next:
cleaning of the distributor cap and reneval of the HT cables but, I really don't think my problem is there as spark plugs were fine and high rmp power is there.
any better ideas to offer?
850 N/A 200k km -94
