Hey guys! Volvo noob here.
I have a problem where my car randomly starts idling at ≈1500rpm and I can't seem to figure out the problem.
I have cleaned out the throttle body and checked for vacuum leaks around injectors, IAC valve, brake booster & other obvious spots. I suspect it may be something electrical since if I turn the car off and on again it'll start idling normally (only when the engine is cold though?) Any help would be appreciated, Cheers?
