A guide to problems, costs, maintenance and repair for your 2004 Ford Thunderbird

The valve cover gaskets may leak oil into the spark plug wells, shorting out the spark plugs, causing a misfire, and illuminating the Check Engine Light. Commonly the spark plugs and ignition coils or wires will require replacement, along with resealing the valve cover to correct this concern.

If you purchase one be sure to investigate extended FoMoCo warranti...

Gave me a new Mustang to drive home. I live 65 miles away from the dealer. No charge for anything except the gas I used. There is a Ford warranty on the 2002--2004 Thunderbirds for 100,000 miles...

ABS Light came on @ 22K miles. This was a $450 fix (one wheel only D/S front) because Ford no longer stocks the sensor only as a repair part. The whole assembly had to be purchased.
