- how long would this fix take a novice to perform? I have done minor work like changing brake pads/shoes and regapping spark plugs, but never any engine work.

Thanks.

Not sure why the CEL comes on only certain times, but I wouldn't worry about it. And it should take you about 3 hours if you take your time. I highly recommend taking off that windshield wiper cover, you have much more room. It's actually not that hard of a job.

In the summer, letting the engine warm up a bit before hitting the road seemed to minimize the occurence of a CEL.

In the cold Ottawa winters, no amount of warming the engine up seems to help, and I am always getting a CEL.
