Hi Scotty,
A friend has a 2006 Volvo S40, 1.8 .
When stoping at a red light, the engine revs itself to 3000rpm for 5 seconds and then drops to normal idle speed.
Code : P2110
Sometimes it goes into limp mode and it's like it's running 2 cylinders instead of 4.
What could cause all this ?
Thank you !
those are notorious for throttle system failures, I've changed tons of throttle bodies out on those. But do try cleaning it first with throttle cleaner spray
