I bought a Code reader today at Sears. $79.00
Rough idle and check engine light is on. Code PO170 and PO173 again.

Last week replaced the Mass air flow sensor. and plugs. 20,000 miles ago replaced the fuel pump and filter and cats.
Also last Friday the Dealer charged me $80 to reroute a vacuum line.
The multi mis fire codes are gone and its now drivable - - but she isnt right.

Still looking for the Cure. I wonder how many MAS are defective out of the box. I am starting to understand why people lease.
