It looks like I'm going to be operating my 2000 Cab with 2 failed cats for a while. The only real downside for me is that this will bring on repeating CELs that I will have to have my indy mechanic regularly clear for me. It occurs that it would save me considerable time / trouble to purchase a basic OBD reader that will allow me to check, then cancel CEL on my own. If anyone has recommendations for such a tool, I would appreciate any advice available.
I took it to the shop and the car shows those system too lean in bank 1 and bank 2, do i have to replace anything?
The mechanic told me we should replace the coils in #4 and #5 because they are misfiring due to something.
Any ideas before i go buying new coils?
I just picked up my new/used 2006 Cayman S two days ago. I filled it up with gas today (did two days ago as well) and about 7-10 miles later the Check Engine Light came on. Shortly after that the Central Warning Light (red exclamation mark next to the CEL light) came on, and the info message said "Check Engine". Guess that was obvious.
I went to two AutoZone stores and they hooked up the CS to their OBD2 (pardon me, but I am new to Porsche and all this stuff) scanner. Both times they thought the device registered something, but when they connected the device to their computer in the store there were No Fault Codes found.
I drove by the Porsche dealer to see if they could find a code, but being Christmas eve they were already closed.
The car had a pre-purchase inspection done at a Porsche dealer, and they did find and repair a fault code, having to do with some charcoal gas vent / canister (evap). That was repaired and the car checked out with no codes.
Can anybody comment on this? Would it be possible to trigger the CEL without the car registering and storing a code? Do the AutoZone OBD2 scanners (Innova was the brand) work on a Porsche (I heard there are primary and extended codes (car specific))? Could the car be issuing a special Porsche code that is not even able to be recorded by the OBD2 scanner?
I appreciate any help and suggestions you can provide. So far my Christmas present is not feeling like a good one.
So yesterday, noticed the CEL (check engine light) came on (not flashing, just solid amber).
Pulled the codes and reset all faults.
Reseated my gas cap to ensure it is fully closed. Since I was almost empty of gas, filled up (not that it is very relevant ...lol).
Today, after about 40 miles or so, CEL came back on again. Originally there were 2 codes (will post update with those), but after reset, only 1 came back (I imagine the other will return soon but we will see).
Pulled codes with Durametric cable/sw, and here is what I got:
Evaporative Emission System Incorrect Purge Flow - Upper limit value exceeded, test conditions are not-completed, fault is currently active and causing a DTC light
Any ideas on what can be causing this error and how it can be fixed DYI?
What maintenance items could be causing something like this? (my first thought - dirty air filters? - i have not checked them yet so do not know if dirty - got the car about 2 months ago).
Any help is greatly appreciated. Thanks.
