  1. Thanks, This vehicle when given a choice will always have problems with the most expensive parts.
  2. Thanks. I erased the codes and today a new one came up, P1133. This points to the A/F sensor. Is this OBD code roulette common? I erased this code and will try again to see what pops up. Its more of a "cascade of failures", one problem triggers problems in other areas. When I had my coil failures, I'd pull the codes and there'd be a bunch codes, but once I cleared them the first one that came back was usually the true culprit. Thanks, I'll be checking them again.

  4. I have a 1999 RX300 with approx. 88K miles. The check engine light came on and I found a PO 171 code. I cleaned the MAF sensor and replaced it. Code gone. Today my wife used the car and the light came back on. I checked the codes and the PO 171 was back with PO 300, PO 302, PO 304 and PO 306. Has anyone else bumped into this series of error codes? Are there any suggestions as to how to proceed? Thanks.
