Part throttle kangarooing

[Wobba]

HAI!!!!

Ok, doing boring commuting everyday in slow traffic is not much fun, especially when on tiny throttle inputs, especially on clutch biting point, I get a kangaroo effect from the engine.

Without gears engaged at standstill on tiny throttle input the revs are inconsistent, they fluctuate across the cylinders. Its not a big problem, but annoying.

I am guessing the following:

Lambda
Dirty injector(s)
Crank sensor
Gunner180 ECU map

Any other options?

It is NOT sparks, HT leads, dizzy or CTS as these are all virtually brand new.

Tanks! :D

I have the same problem, would like to know a remedy

ran a 180 chip no problems with low speed running or idle

[busterhymes]

is problem worse when cold or same across the board

Mines ALOT worse when cold, it feels more like misfires

[busterhymes]

CTS, lambda are fav culprits when cold but basic checks on such things as plugs, leads, distributor cap always good to do

all my f7 powered clios have all done this, very very slight it is and same with holding revs on. never bothered me, figured old wiring= old earths = crap electrics and assciated issues

With mine, if you are just very lightly holding revs as you say, you can hear it fluctuate, as if one piston chamber is less fuelled than the others or one more than the others if you see what I mean.

mines doing this too, i think its the vacuum pipe that goes from the map sensor to the inlet manifold, behind the drivers headlight. (probably blocked or split or not properly connected to the manifold)

as when i play around with that pipe it seems to make the problem worse/better.

Gonna have a proper look when its a bit warmer!

Interesting you say that. I have a pinhead hole in mine. may replace it and see what happens...
