Well I finally fixed Melinda's car.
It has been smoking out the tailpipe for almost a year.
It started smoking only at a hot idle, then it gradually did it all the time, even while cruising the expressway.
You came off the expressway and you would be enveloped in a cloud of smoke.
Was not loosing coolant or oil and the smoke smelled like the inside of a foundry.
It was embarrassing and it was pissing us off like no tomorrow.
Our MPG had dropped too.
So one night while in the shower I had a idea, so I went to AutoZone and bought a can of CRC MAF cleaner.
Cleaned the MAF and BAM!, car is fixed.
No more smoke, runs great and MPG is coming back up.
$7, glad I did not drop the $$$ to buy new O2 sensors and a catalytic converter for it.
