Check Engine Light - 986 Forum - The Community for Porsche Boxster & Cayman Owners

waterboy · 03-03-2008, 09:23 AM

I'm a fairly new owner of a used '01 Boxster S with 70k miles. While doing a PCA Drivers Ed day last Sunday the check engine light came on. After viewing this board I was happy to find out that I could go to Autozone and borrow their scan tool to check for codes myself.

I have a P1130 & a P1128 code "Manufacturer control fuel/air metering". I cleared the code and have driven the car for a week and check engine has not returned (yet).

Should I take the car to a mechanic to be checked out. Is there anything I can check myself?

Any help is appreciated...love this forum - I've learned a ton.

What a horrible time to get a CEL. Those were the codes that I had when my MAF went out. Have you done any recent work on the car or installed any new modificiations?

I've made no changes or modifications to the car. It is completely stock, no intake or exhaust upgrades.

When I bought the car from a local 'high end' car dealer a year ago, I got a CEL. As it was under 30 days of purchase the dealer 'fixed it'. A couple weeks later I got another CEL which the dealer would not cover as it was just after 30 days. A local mechanic discovered a cracked emmissions canister. This was 9 months ago, and the car has been good since then.

From reading this forum, I'm wondering if it just might be time (70k miles) for o2 sensors or mass air flow sensor.

On the other hand, it might be fine for a while. I was just wondering if I could be doing any damage to the car by continuing to drive it.

I heard from another guy at the DE day that his Boxster throws CEL 'all the time'.

BTW - I love this car...and had a great time at the event. It rained all morning so we got lots of 'sideways' time. Great to finally get to drive the car 'vigourously' in a proper environment.

You can try cleaning the MAF as thats basically free. There are a lot of past threads here on how to do that.

Your car is running lean. Could be a bad/dirty MAF, also could be an intake air leak. You will probably want to fix this soon. Running lean is hard on the motor.

I was at the DE, it was great playing in the rain although my windows kept fogging up! I was in the green run group with a red boxster that liked to smoke in the figure 8 turns. if you want to relive the mini AX at the end i filmed a few laps http://www.youtube.com/watch?v=r_fF06-qWgw . You doing the autocross next weekend?
your CEL sounds like the MAF is the culprit... try cleaning it yourself first.
