Could you more knowledgable people point me in the right direction of what to check on my starlet?
im competent on cars but relatively new to the starlet so dont know what if any vac pipes/sensors to check.

my glanza drives absolutely superbly,but when idling it will drop a few hundred rpm for a second,when it drops it kind of pops from the exhaust like a real tiny misfire.

i've cleaned the i.c.v with no change to the fault.

plugs & leads are new.

what's next to check?

cheers

Check the earths on the battery. Poor grounding can cause small variations in idle speed. Especially when stop starting.
