Help with Engine Fault Codes
Hello all,
Just picked up the 2001 Boxster S from the dealer today.Third time picking it up as he was supposed to clear an engine light before I accepted the car. The first two times he changed O2 sensors and today he changed the MAF sensor. Car drove fine 30 miles home. I came back and changed the engine oil and filter and took it for a drive. After 10 minutes Engine Light came on and the same two codes as before were read out. P1133 and P1126. Now I am a little lost. Do I keep letting the guy try to fix it or does anybode recognize the problem? |
How is the performance?
Does it idle and accelerate well? |
It idles fine and steady. When opening the throttle it sounds like it is gasping for air and then it kicks in. Above 4000 rpm there is no issues at all.

If it were me, I'd see if it runs better with the MAF disconnected and check for vacuum leaks. Make sure the air filter is new, or at least not too bad.
If it runs better with the MAF disconnected, it either wasn't replaced or is defective. Vacuum level can be tested or you can do a smoke test. There are many suspects for vacuum leaks, but a prime candidate is the oil fill tube. |
Roger that. Air filter was replaced today. Will try to disconnect the MAF tommorow and take a drive. Thank you for the responses!

I had problems with 1124 and 1126. It turned out to be a vacuum leak. Indie found it with a smoke machine.

Where was the leak? |
I dug out the paperwork and it doesn't clarify. IIRC something came unplugged up under the throttle body.
