Throttle still sticking
Hi all, I've had a long running issue with my 190, where every now and again my revs will stick at around 2.5k when I put the clutch in, until I tap the throttle and they drop back to normal.
I've replaced the iacv, checked and lubed the cable, and given everything a good clean, but it's still happening. It looks as though occasionally the spring isn't returning the butterfly all the way closed, and if I press the linkage down it shuts. I'm guessing the butterfly return spring is getting worn, or there is more grime in the linkage area that I can't get to. Any ideas on how to sort it, or is it just a case of replacing the tb?

Have a look inside the throttle body, it may be gunky in there

Do they have a throttle position sensor on the pedal?

I've cleaned all inside the tb, the only place there could be dirt left is inside the actual butterfly spindle that goes through the tb or inside the spring mechanism.
The only way I can see to clean that is to actually disassemble the spring mechanism from the side of the tb and take the butterfly our, which I don't really fancy doing! |
