I'm experiencing the same rough hot starts,though mine won't pass the idle test of our Aircare program.I failed miserably the first oh so innocent trip through,took it to a local import shop and he said O2 sensor,bring it back next week
.So I replaced it myself and tried again,failed,but only the idle test this time.Hmmmm,pulled the plugs and noticed they were NGK resistors
,in went Bosch Super's and a bottle of snake oil guaranteed to make your exhaust cleaner than clean,failed again.
So I went by the repair shop today,really nice guys btw at Valley Eurotec in Abbotsford,and they figured it was the injectors being worn out,sputtering too much fuel at idle,making it fail the idle test.It's going in on Friday to have injectors installed ($240+ labour)and another Aircare test (@$24ea).It BETTER pass!!
