Cleaning throttle body myself
 

Is there anything to watch out for when cleaning the throttle body?
What kind of cleaning solution should I use? Carborator cleaner or something?
How sensitive is the sensor(s) on the unit? Use a brush or Q-tip?
Any parts I should buy for replacement before taking the unit out?

Make sure you buy a new throttle body gasket.It will be a metal gasket.

Also remove the bracket from the starter to the block.This will allow the wiring for the throttle body to come out so you can remove the throttle body all the way.

I use either carb cleaner or brake cleaner.They are both fine to use.If you buy a good quality cleaner you will not need to use a brush or anything like that.

Is your car turbo or non-turbo?

do not use carb cleaner this will force the chemical pass the seals on the shaft and damageing tha throttle module this damage may not happen right away. cleaner h is the only aproved cleaner. use an acid brush and some non lint rags

At the dealers Carb cleaner has been used for years with no problems at all!!!

With the Prices of the cleaner H at about $30.00 to $35.00 for the entire can I don't think many people will buy it.

Tech, Specifically what needs to be cleaned on the throttle body? I'm wondering if I can just point and spray carb cleaner at the butterfly valve. I'm not opposed to pulling the ETM off if that's what's needed, just need to know what to focus on.


My '01 S80 decided it didn't want to start after sitting out for a few nights in sub-zero temperatures. I had it towed to a shop where it sat inside overnight and started on first try the next morning. A couple of fault codes were pulled that pointed to the ETM (codes: 91B7 and 130A). For the past two days the idle has been somewhat rough and the exhaust smells rich, but the more i drive it the smoother the idle becomes and the rich smell is going away. So I'm wondering if the failure to start may be connected to dirty ETM.

software update maybe the cause ?
i dont think a dirty TB will cause this, a dirty and partially clogged fuel filter may cause this in really cold weather, but the problem goes away after you manage to start the car...

whoever does this TB cleaning please take some pictures... proper walkthroughs are so hard to come by for these cars ...
