The AC is cooling, no problem there, and I can get cold air from to defroster vents and floor vents in the front, but it is no really blowing from the vents in the dash. This just started today

the check engine light goes out after I remove the negative battery terminal, but comes back on after driving for about a week. auto zone tested it and gave me the code po451.

after each is displayed it then reads something about power is reduced- What or why would this be displayed --what type of service is needed.

it is better since we got new tires and an alignment but still does it once in a while.

can a leaky water pump cause your steering wheel to lock up when you come to a complete stop (FYI) i just had my car serviced because my power steering was failing.

i had my power steering serviced, was failing

I replaced the purge solenoid under the hood that didn't help. I don't have to fill up it does it when I put 3 gallons in. I have a code po451.I need to know where the vent valve solenoid and canister are. Or would those be my problem?

Is it true that all buicks have this tic. They are saying that it is the direct injection.

Do you need to change the whole unit if your struts are still good and not leaking but the mount is causing a knocking noise on bumpy roads? Why can't you change only the mount and keep the struts you have?
