Re: 90 wont pass smog
Tom;
The smog test requires bringing the idle up to 2500rpm and holding it for a short period of time. What is taking place is, at the 2500rpm the idle will drop down by 400 to 500 rpm and then will go back up to the 2500rpm. If just sitting in a normal idle condition, it is around 950rpm but will increase to 100 to 1200rpm then drop back to the 950.
Here is some information I got from the dealer. I don't have an actual read out because they didn't want the car going into the system and be labled a gross polluter. But they gave me the are of failure which is co reading. The left bank is fine, it's the right side that the reading fluctuates, from 65co to 450co.
Sorry if my original post on the rpm was vague.
Everyone, your help is really appreciated.
Tony
