Just had codes pulled last night -

P1506 (IAC overspeed error) which points to a bad IAC valve or a vac leak. IAC has been replaced, so for the 1000th time, I will check for vac leaks.

P1131 (lack of bank 1 o2 transitions - lean) which points to vac leak or fuel injector problem.

Maybe I should just hit the craps table instead.
