general problems of the 2002 Oldsmobile Silhouette

I could not get my van inspected last oct as the code came up po 446, we were told to drive 50 miles, then 100 miles, didn`t correct this we tried for 2 weeks . We were going to florida for the winter,and stopped in waverly NY to see if the 150 miles to there would correct this no, while we were in FL. In Feb. I had a mechanic check out the car , he changed the oil and all filters ,new plugs and wireing and a . A. I. R. Check valve. Part # 911004. . . The po446 still came up . In April he put in a canister vent soleoid part # cvp124 and purge valve part # 9110117 we have had this in for inspection twice and today the failed report said I have a 10 day extention to get it fixed and no other extention. I am stymied,I paid over 1500 I was told in FL by the mechanic he was sure this was all correct and I would be able to pass inspection. If I thought all this money I spent on all this work I would have done a different route the van runs great. We are sno-birds and in our 80`s and can`t afford to just buy another van. I paid over $ 1500. And at $3. 00 a gallon for gas after putting miles on to correct this code, and $`s for failed inspection . I am out a lot of money and can`t drive my van after 7/2/17. Please help.

My 2002 Oldsmobile Silhouette completely shuts down while driving. It doesn't matter if I'm going 30mph or 65mph. Everything stops. This is a scary dangerous situation while highway driving! the car is otherwise perfect and has 47k miles. I brought it to the dealer last November, and was told they don't know what it is. I contacted gm three weeks ago, and now it's back at the dealer. Help, please.

Slowly but surely, some of my electrical systems have been failing. It first started with lights burning out repeatedly, then went to turn signals not working properly, then went to power windows functioning improperly, then the temperature/mpg/oil display stopped functioning, then I had to replace the alternator and the problems got even worse. I have also had issues with the vehicle drifting up to 3 feet backwards if on a slight incline and in drive. Please check into these issues and resolve. I am scared for my family's safety due to the increasing electrical issues. I am beginning to think this may be a fire hazard. We have tried replacing the switches for the windows, the bulbs and tail light assembly. The issues with the windows get better when the switch is replaced and then get even worse than before in no time flat. In addition to these issues we have had to replace the bearings repeatedly.
