Replace MAF, Cleaned Throttle Body-Wow!


Recommended Posts

Hello Everyone!

Have been a lurker for several years; this is my first post. I have some information that may or may not be useful regarding MAF and throttle body. I bought a 2000 Boxster S in 2005 with 8600 miles on it. It ran nicely, but had evidently been sitting for a while. I replaced the tires and instantly got a much better ride. After a couple of months I got a CEL (I believe it was P1126). Happily, I had found this site and learned all that I could about the problem. I recalled one post where a gentleman said that he had a similar experience on a low mile car that had been sitting for some time and that he solved the problem by simply cleaning the MAF with electronic parts cleaner. I did this and it worked like a charm for over a year. Eventually the CEL returned and I cleaned the MAF again, thus saving money once more. It lasted another period of months before I got another light. I figured I had ridden that MAF sensor as long as I could and bit the bullet and ordered one from Paragon Products in Corpus Christi for about $240 US. It got here quickly and I installed it today. While I was in the engine bay I decided to clean the throttle body as my idle had been a little jumpy for a few months. Took it out of the car (I have some mechanical skills from helping my dad restore cars 25 years ago when I was a kid) and cleaned it with carb cleaner in the manner prescribed by this site. The car only has 30,000 miles on it now, but there was a significant buildup of carbon or whatever gets in there in the TB. In any event, I was fortunate enough not to have much trouble getting the plastic hose on and off and I think Loren is correct when he says having the car warm (not hot) can make this process a little smoother. Anyway, I cleared the CEL and took her out for a spin. I waited way too long to replace the MAF! I forgot what this thing can run like. I shifted into second gear and spun the tires enough to kick on the traction control and these are brand new summer tires. It's good to have her back. Hope I didn't bore you to death, just wanted to say that if you have MAF problems, cleaning it will shut off the CEL for a while, but go ahead and replace it. It's worth every penny.
