Do you mean spark plugs? I'm a car noob.
If I need to replace the plugs (very unlikely), and clean the MAF sensor, any idea how much will it take? I don't want to go to the dealer any more.
Thank you!
Yes, Mr. M- That would be spark plugs. They put some of the finest plugs known to man in these cars. Even my wife's '02 Camry 4cyl came with them. Cost them a few $'s apiece for Toyota rather than a few cents apiece like our American manufacturers. They list for around $19. each and can be purchased online for about $8. ea. Don't confuse them with the Platinum Denso's that Autozone sells for about $8. ea. You might consider taking the plugs out and checking them, fine wire brushing them and maybe a little bit of carb cleaner, but only because that's an all aluminum engine and when I changed My DIL's at 97k (not knowing), one of the rear plugs came a little hard because it had 97k mi of crud on the threads (yes, it's possible for carbon to get up on the threads over a long period of time), and I was afraid I might gall the threads and really be in trouble. Didn't happen, and I put a very small amount of anti-seize on the threads when the new plugs went in.
As far as the MAF sensor, there are GOOD instructions on cleaning it on this forum and ANOTHER popular Lexus forum. It's not hard to do, you just need to know what to use and how to be careful in the cleaning so that you don't damage the delicate sensor parts as you are cleaning. I would rather you read those instructions rather than me repeating them so that there is no misundertanding. You should have no trouble doing it. Make sure to get and use the right cleaner. It's still the 1st. thing I would do.
Thanks for the detailed answer. Today I took the MAF sensor out and took a close look. The air temp sensor is easy to inspect & clean, it was covered with oiled dust, I managed to clean up most of them=;, but the inner stuff is really hard to see clearly, even with a flashlight. I went to the auto parts shop and tried to find some MAF sensor cleaner but wasn't able to. They have fast dry air intake cleaner and carbon cleaner. Can I use the air intake cleaner?
