Erractic Idling

[Ex_vagrant]

Dear MCFers,

 

I've installed the Simonta open-pod air filter (replaced my KNN drop-in) and the car feels more torquey in low-end. I'm driving the 91 Suzuki Swift 1.3.

 

However, the idling is erratic at 1000 - 1500 rpm and after you rev and let go of the pedal, the rpm stays there...??

 

Any kind advice or any good old-mechanic to check/tune my carb engine? Could be it due to the higher airflow causing this?

 

Thanks in advance...

Have idling problem on my 92 Swift too...Dont know why recently it drops to below 1000 rpm after engine has warmed up. Used to be at approx 1100rpm(no a/c), 1300(with a/c)

could be caused by dirty throttle body

Thanks. I'll get my mech to check...
