I just did the plugs and ipd coils so Idk. My car is slow and rumbling between 2-3k rpms especially between 60-80mph (4th gear?).. any idea what could cause that? 02 s80 t6.

Also I think my fan is dead.. connected properly but caked in oil.


Thanks.

 

Plugs gapped to .028"?

 

Yes bought oem plugs from Volvo and checked the gap

 

common problem after a tune up is pinching the wires between the valve cover and the plastic cover. lookin for a gray with black strip to be pinched.
