So what went wrong?
I bought my 02 Bonneville SSEI in July of 08. she had 73k miles on it. right after i purchased i needed to replace the LIM (common problem). I also had the Cat replaced it was bad before i purchased the car. All was fine until a few days ago when the idle started going up and down slightly and would stall, in gear when stopped. at the same time a heard a knock under acceleration. I drove about 10 miles to the Pontiac Dealer. There diagnosis was i have a ROD KNOCK. I picked up from dealer, driving to a Mechanic for a 2nd opinion and the ROD let go.
I know these cars have there problems. I can can accept that... But...... Throwing a Connecting Rod at 75k Miles?????
I suspect the car was abused before i purchased and perhaps had a a rod knock and someone dropped the pan and threw a bearing in just to get rid of it.
PS... I never ran it low on oil. The oil had been changed just before i purchased. i have only put 2000 miles on this car since i bought it
