It's a bit cooler here now (-12 degrees Celsius ..about +10 degrees F)... this morning I was letting the engine warm up a bit on my 90LS while I scraped the ice and snow off the windows ...and I noticed a very strong gasoline smell from the exhaust. I had changed the o-rings on the injectors this past summer (they were not visibily leaking) because of a gas smell at the front of the car ...now I'm wondering if the fuel mixture is way too rich. Any way to adjust that???
