Questions & Answers

Mechanic Q: catalytic converter?

I've always used premium fuel (as recommended), but have been told that Giant Eagle's Get Go gas is inferior & can cause catalytic converter failure. If this is true, what would be the approximate cost of that part (not counting labor)? Their comment was based on a "lean" smell to the exhaust. Is there a hook up spot to get a computer diagnosis code?

A: something is draining the battery?

Thanks, I'm asking my mechanic if he did this test.

Mechanic Q: something is draining the battery?

What can be checked when there is a drain on a new battery? It will start if done every day but won't start if it sits for 2 days. No lights are left on & radio & auto air/heat is off. Under hood light has been disconnected.

A: antilock light stays on?

I'll follow up on your suggestions, but I've tested the ABS in a safe area by forcefully applying the brakes --- there is the typical shuddering of the brake pedal that accompanies ABS & skid is controlled without the pumping of brakes that are necessary when there is no ABS. Thank you for the informative suggestions.
