hey guys first of all i know theres a search bar yea but i looked for 5 min and couldnt find anything and im the most imatient person ull meet

my car is buggy at low rpms amd idles rough, heard it might be due to a dirty MAF sensor. Anyone that can help me with its location and how to remove and clean it with the spray? i know its located next to the intake box

much appreciated

 

What car model do you have? If you have the IS250, it's more likely the carbon build up issue. Lexus has extended warranty on that issue for 9(?) years and unlimited miles.

 

The MAF is located just to the right of the filter box, on the intake tube and faces toward the cowl.

really? its a 2006 is250 and i know of the issue but was unaware of the inlimited miles/years, also i bought the car used and i am pretty sure the original owner had that done at the dealer (i'll attach a pic of service records) not sure if thats what was done or not. thank you!



thanks g, exactly what i was looking for

 

Better just to buy new MAF sensor.

 

yea i know but i may as well try a $10 fix before a couple bills lol struggling college student over here

 

I'm not sure what you mean by "buggy" but if you mean it sputters sometimes, its prob carbon buildup. The dealers fix only slows carbon buildup down, so symptoms can return. If its really a problem you can have the dealer, or some other shop do a top engine clean. I had the carbon buildup fix done 30K miles ago, and there have been a few instances of sputters, but not enough for me to bother with a cleaning. I highly doubt its the MAF, unless you have a K&N air filter which uses oil. I guess cleaning it cant hurt, but i certainly wouldnt waste money replacing it.

 

i see, and is the dealer fix for the carbon build up up to unlimited miles and years as the previous user suggested on the post? when you took urs in was it still under warranty? thanks man

 

The year is not unlimited ... I think it might be 9 years; so check your service records on when the car is sold to a person. Also, what you posted looks like the carbon build up fix. When was that done? Normally, the Lexus dealership will warranty their work for 1 year and some number of miles.

 

it was done in 2013 so unfortunately looks like out of warranty. also just called my lexus and the car is over the 9 years so its out of the warranty for that too

it costs $600 to do the engine cleaning and the rep also said he recommends a $200 cleaning of the intake and things which he said should be done every 30k miles. what do you guys think? should i try to find a better price for the engine cleaning elsewhere or is it something lexus knows best and i should have them do it?

 

There is no cleaning of the intake every 30K miles -- there is replacing the engine air filter if the previous owner didn't do it (you can easily do that yourself). I'm not sure about the cost of engine cleaning on the car; my brother's BMW needed engine cleaning done that was about $200 in a shop.

sorry i meant to say intake valves and things like that, and the sales rep said he personally recommends that for direct injection engines. thanks I'll look into another shop for the top engine clean... seems like this is a common problem with these engines

 

Yes the dealer is going to be alot more expensive then a private shop. One company that makes reputable engine cleaning products/services is BG. You can you use this link to find a shop that uses there products/services http://www.bgfindashop.com/locator/index.php
