Santro Speed Throttle Stuck

I have recently purchased a 2002 model Santro Plus (MPFI). This type of model did not come with CNG Kit installed. The person from whom I have bought this had the CNG Kit fitted later, manually. The problem is that on petrol the car remain in high RPM even when idle, as if its speed throttle is stuck. When on CNG it behaves the same except that after 5 or 6 seconds the RPMs returns to the normal range. This constant high RPM are also causing a little bit of over heating. The accelerator pedal wire is fitted right, I have checked it under hood as well. Don't know what's the problem. Could it be the ECU?

From Carby point of view, there can be two things affecting,
bcoz there would be some alternate function made in MPFI.

1 - There is one Screw in throttle that adjusts the speed (accelerator related), that might need to set.

2 - There is one throttle screw that is used to fix the Stand-By fuel. This one is long one. In Khyber, I need to get closer than brake drum/viper connection to see it rightly.
