hi... requesting some wisdom...

have an '01 9-3SE w/100k... last month while on a road trip (about 400 miles) my AC compressor failed (bearing)... had compressor replaced by local Saab shop (indie, highly recommended) and they also replaced the fuel filter and flushed AT system... car ran great but at end of drive back, after stopping for gas, CEL came on while starting car... seemed to run okay, so continued home and had code read a local smog shop... P1334... called distant Saab shop (now 400 miles away) and they said nothing they did would cause this... likely DIC or plugs... had smog shop clear codes and installed properly gapped set of new OEM plugs... also purchased used DIC from ebay (yea!)...

car ran great for about a month, but last week car stumbled (but didn't actually stall) at a stop sign. no CEL, but next morning when starting the car the CEL came back on. pulled fuse 28 to clear light and installed ebay DIC. all okay for 2 days but then CEL came back on after starting...

took to local Saab shop (not dealer) who found same P1334 and P1312 codes and said they might have been left over from first DIC (?!?), cleared codes and said all was okay...

next morning (you guessed it)... CEL back on...

now i can purchase a new DIC (for about $350 if i can find one!) but it feels like we're guessing... i suppose i could have replaced a bad DIC with another bad DIC and the fact that this all started after the service for the AC and fuel filter replacement is a coincidence...

any thoughts on how to really zero in on the cause?

(btw, car seems to run okay on the highway... lots of power and gas mileage is where expected... but feels a bit 'rough' to me at idle even when CEL is off)

many MANY thanks in advance!
robin
