A/C wiring connections

Hey HASSAN SHUAIBU,

Does the same thing happen when you turn electrical loads on?

Does the A/C work?

Turn on all electric items eg. headlights, rear window defogger, wipers.

If this load does not affect the idle then you may have an issue with the the A/C compressor.

How is the idle generally?
Stable and smooth?

A good place to start would be to clean the throttle body on your vehicle. Guide below:

Also check for vacuum leaks:

I do not have the specifics for your vehicle but i would also advise checking your idle control valve and cleaning if necessary.

You may be able to find a guide for this online.

If you post some pictures we should be able to identify the items you need to remove/clean.

Hey HASSAN SHUAIBU,

If you can follow the guide below and scan for codes that will be helpful in getting this fixed:

It sounds like your idle control is not working.

The guides from before for cleaning throttle and checking for vacuum leaks may find the problem but it will be quicker if you get the codes.

Hope that helps.
