Duke,
Thank you again for all of the information!
I did a search on my engine to find out if it has the KE injection and I learned that is has the LH system. Would I continue to look at injector valve wear as a possible cause for the higher emissions? The car idle is good but then again I really don't have a new car to compare it to so who knows. Again I'm not stressed about this I just want to figure out what can cause the changes and what I can do to help for future tests and operation.
Rich,
I'm encouraged to hear the cats are not the issue as each costs about $1000
. I'm thinking about taking the car in for further testing in the future but I really want to get a handle of what would cause the changes and if they can be addressed easily or not. I appreciate the info!
