Lanos Flat spot

[Banginman]

Hello. Lanos 1.6sx has a flat spot just off idle.Mostly when engine is cold.Its better when warm.I have fiited a breather filter to reduce the gunge sucked into the throttle body hoping this might help the problem although it seems more responsive the jerky running is still there.Any ideas, please?

problem with rpm?

[Banginman]

No problem with idle,does hang around 2000 rpm then drops to 900-950.Just feels a bit on the lean side.Is it possible to richen the mixture?

[buddha102]

it is possible but u have to fuck around with the ECU, and thats how far my knowledge gets

maybe ur injectors are dirty? maybe thats why no?

when my engine is cold, it trys to died on me, i think it is my injectors, but not sure.

as soon as my engine has been rung for 5-10 in it is fine,
