iddle issues

Hi, I´m from Costa Rica, have a 2005 petrol Jimny, need help because I have some trouble...

When I have lights on and stop iddle is goin down... from 900 rpm to 500 rpm... then the car move so strange...

Change everything you think: iddle valve (and sensor), filters... etc. What sensor will be bad???

Sorry for my english (I don´t speak from 10 years... I think)
Thanks for all and Pura Vida!!

some thing is causing a drain on the eletrics have you checked the output/charge rate on the alternator your revs should drop a lottle but then come back up to normal

Have a look at the stepper motor.

Thanks never thought of these parts
this problem is driving me really mad

As I said, I changed plug wires, spark plugs, fuel filter and air filter, idle sensor ...

Now we just need to change TCP sensor, MAF and Lambda sensor (perhaps be cause of the problem of idle?)

Suzuki scanner only reads ECU (I think Hana tech or Tech 2 Bosch) in Costa Rica almost no mechanical with this tool ...

Thank you very much for your help with this I have new ideas to fix the Jimny
Pura Vida!
