Any sensors you can clean?

[AmDaMan]

Hi, just wondering this as my 172 is being a bit sluggish lately on partial throttle and the idle is wandering a bit..

Theres no airleaks and the TB has been cleaned and isn't very old.

Just wondering if there are any common sensors you can clean up or check? There are no faults reading on the ECU but partial throttle can cause it to kangaroo sometimes, but the next second it's fine, kind of a patterned issue?

cheers

how olds ya lambda sensor.
Just put a new one in mine (with a 182 manifold ) and so far am noticing slight increase in MPG. Although idle is not really any better

hey mate, not sure, but it's recently passed it's MOT and no faults showing?

It's just so annoying in slow moving traffic when it's fine then suddenly kangaroos!
