What a bummer this has been... I replaced my engine coolant temp sensor and that went fine. I removed the plenum partially to get at it and removed the large vaccuum hose from the throttle body. I also moved around a bunch of wire looms. I lost a bunch of coolant when i removed the thing (opps)...

I put everything back together and checked the hoses i removed. I started it up and 3 minutes in I hear the engine bog down al ittle and my happy check engine light goes on.

I Vagg'd it and got P1101 and P1106.

Could the coolant I lost get onto some wires and cause these codes? Could a vacuum leak? I really have no idea what went wrong and I have work at 8am!

Help!

 

Those a codes for leaks on both banks, check behind the engine and make sure you didn't knock a line loose or something.

 

I'll have to check in the AM. What vac lines are behind the engine? I thought they were all as shown here:

 

Thats a schematic, it doesn't show exactly where the lines are. I see you took off lines from the throttle body as well, did you get the right hoses plugged where they were supposed to be? I would check that as well.

 

Yeah I'm thinking I pulled one off somewhere since both banks are reading that there's an air leak. *sigh* 6am here I come...

 

OH ****! I think I know which one it is! there's a ittle tiny line that goes from the plenum to the TB... I bet that's disconnected!

 

Yep - There's a tiny vac line that goes from the throttle body to the plenum. Rexonnected that and everything is good now.

You win a cookie!

 

Ha ha, i wonder how many cookies i can win from you in a year.
