Induction cleaning for cars?

[NAKID]

The mechanics said a cleaning could have prevented it - I don't really believe it, but who really knows. mitt

That sounds bunk to me. A TPS is a pentiometer, changes voltage when the butterfly moves. How cleaning the intake would have prevented that is beyond be. TPS's go out because of electronic failure...

Now I understand what you were asking. BG makes some great stuff for that. As far as I'm concerned they are the leader in the industry.

Oh and I've used seafoam before too with good results.

I've used GM-branded induction cleaner. Didn't do anything, but then again, that wasn't the problem to begin with. And it did absolutely nothing to remove the heavy carbon deposits from our Mercedes 6. How do I know? Because we yanked the head off to replace the gaskets a little while after, and it looked like a hardened volcano inside. Never tried Seafoam, mainly because I've never "needed" it. The last time I "cleaned" my heads, I took them off and rebuilt them. That's the way I do it, rather than putting my faith in any miracle product.

It is bunk.  A dirty throttle body can cause two problems.  One is the throttle being held slightly open when it should be closed, the other is wrong air mass input because the hot wire is coated with gunk.  If you do this yourself be careful around the TPS, solvent can kill it.  The hot wire is also delicate.

Usually an air mass meter is further up the intake by the air filter.  Havent ever seen them as part of the throttle body.  The throttle position sensor is on the outside of the throttle body and should not be affected while cleaning the throttle body.  If the car has an Idle air control valve, that could be mounted in the throttle body.
