Hi,
I did a throttle body valve cleanup on my megane couple of months back and have been driving it regularly since to let it learn by itself the new positions for the valve. Seems like the idle is good normally when I start it but gets up to 1500 - 2000rpm when I any of the following:
1. on idle, I press the gas pedal once
2. while driving and slowing down using the engine and press clutch down when rpm is somwhere around 1000.
Any of the above and whoosh! Up in the 1500 - 2000 rpm range again!
I suppose it's not getting better by itself and I haven't found a single good solution for it. All the so-called relearn or reset or reprogramming that I've found haven't worked. I tried also removing battery cable and let it wait few mins but no change.
One funny detail I found out today when the idle was high again is that if I switch the air blower from 0 (stop) to 4 (highest) and repeat it few times, the rpm starts fluctuating up and down in correlation with the air blowing speed. After a few times rpm drops down below 1000rpm and stays there. What in the..? It doesn't help if I keep it high for long as the rpm soon compensates it but twitching it off and high seems to make the fluctuation to the rpm reading.
I don't have any idea anymore on how to try to solve this by myself, any good tips? I'm checking tomorrow if there's any air leak near the TB but I doubt it as the idle is steady most of the time. Maybe I'll stick some glue to the freaking valve so it won't give too much air, getting really irritated with this :frown2:
