2006 Volvo XC90 2.5t Engine surge with a/c on?
I have a 2006 XC90 2.5T, The engine will surge only when the a/c is on. I can feel it drag when I am driving down the road, and when I stop. You can see the rpm's going slightly up and down......Is this a sensor issue or possibly low on freon? The clutch on the a/c is engaged when this surging happens!
Thanks

Yeah I replaced the tubing, charcoal canister under the manifold, but u should try to clean the throttle body first sense is the easiest and cheapest solution, see if that does the trick I just happen to do both at the same time due to the fact that i also had smoke coming out the dipstick which normally indicates a clogged pvc system.

If your clutch is going out on your compressor it can add an extra load. If all else dails you could replace that
