1990 Buick LeSabre Q&A
1990 Buick LeSabre Question: why would my car hesitate and miss out when I first start up and take off.
What size engine? If it is a 3800 these had a problem with the magnet falling out of the cam gear, it may have only come loose on yours causing the dtc code. these can be fixed with JB weld with extreme carefullness..Note if the magnet come out completely the car will not run, if ignored the condition will get worse.these magnets were only held in with a stupid plastic retainer: bad design.. - Tbone1980
COULD ALSO BE A POSS HEAD GASKET LEAK - globalhelper
Common guys this car is almost 24 years old. It could be anything! Maybe a bad timing chain?????? - PARTS GUY
