2002 VOLVO S80 2.9 (non-turbo) the plugs for non-turbo lines are leaking oil and have to be replaced. The mechanic says it's about 5-6 hours of labor. While the car was up on the lift I could see where these lines are and how the plug is missing. It appears to me that these plugs can be jimmied in somehow. Is that the case or does the mechanic really need that much time to plug the lines. In addition the mechanic said I would have to replace the breather valve, another two hours of labor. Is th

We are a one vehicle family so I hope that someone can provide some insight on my problem. Our 03 Windstar was running rough and diagnostics indicated plugs / wires were bad on cylinder 1 and 2.

It will stall out during idle. When in gear at a light I have to power brake it to keep it running. And the battery lig

I have a 1995 Nissan Maxima. I changed the spark plugs and I forgot to reconnect one of the wires to the spark plug. The check engine light came on and I saw what I did and fixed it. Now the check engine light will not cut off. I took to Auto Zone and they hooked up the code scanner and it said miss fire. Which would have been from the spark plug wire not being hooked up. How do I reset the check engine light to have it cut off. Thanks Jimmy
