Engine stalling and idle problem.

[sun valley]

try the basic tune up process also, spark plugs tension wires, coils etc. i might be wrong but it never hurts to try

thanks for the reply, already change spark plug, fuel pump, ignition coil(inside the distributor) cleaned maf sensor, throtlle body, Idle valve with contact cleaner, still the same rough idle and stalling, no check engine naman. Appreciate all the feedbacks, thank you.
