1) EXH light is a mileage thing I am pretty sure. There is a reset button back there somewhere. Search on Saabnet. I am sure it will turn up. This is only on the CIS cars (8V here in the US) 2) normal. You are creating a big vacuum leak by opening the filler cap. IIRC, It screws with CIS more so than LH. The gasket under the cap is pretty important, too. It is probably pretty hard by now and should be replaced. DO not think it is available separately, but one can be made from a piece of rubber... McMaster Carr or local inner tube? 3) This is an 8V, no? Never done it on an 8V, but guess it is probably similar to a 16V. remove distributor, replace oring, replace distributor, set timing. Good luck. KeithG Dave Hinz wrote: > I've got an '86 900 that I'll be driving until I get my 9-5 going again. > (long story, not important right now).
