Thanks for posting that, looks like you have one hell of a diagnosing machine.
Quick question. I'm still chasing a vacuum leak somewhere, did the PCV valve and hose, all the intakes, looked around sprayed the cleaner to no avail. Debating taking off the intake manifold and replacing hoses etc.
One thing I do know is that my rivets leak when the SAP pump is on. I figure that it leaks when the engine is running as well. If I squeeze the top back on the canister the leaking air sound does NOT go away. I figued that if the pump is leaking on the intake side, it is before the MAF thus that air is metered.
Just wondering why Secondary Air pumps get tied up with the 1174 code? I thought they throw a 1423. |
