I have a 1998 S90 volvo, I have a cylinder number not firing, I have changed the plugs, I check the coil on another cylinder and it works fine. I now know that the wiring to number 5 is bad or something is wrong, one mechanic told off the top of his head it would be around $440 to $500 to fix. 2 months ago I had a complete head gasket done and the car was running great. Now it's running very rough on the 5 remaining cylinders

I need a better answer or solution, I can't believe after almost a complete tune up that it takes another $600 buck to get a cylinder firing and the car back to normal?? Can you please give me some answers?

 

Hi Kim, welcome to the site. I left feedback on this issue in the S90 section.
