ENGINE LIGHT COMES ON WHEN ACCELERATING.THIS ISSUE JUST STARTED TODAY. SINCE JULY 2010 I HAVE SPENT CLOSE TO $4,000 TO KEEP THIS VEHICLE RUNNING. THE CAR ONLY HAS 31,000 MILES. I HAVE DEALT WITH KNOCKS, OIL LEAKES, NEW GASKETS, REPLACED THE AIR CONDITIONER AND ALL THE FLUIDS ETC. WHEN SHOULD I CALL IT QUITS? THE CAR IS OUT OF WARRANTY. SHOULD I TAKE IT BACK TO THE DEALER TO CHECK OUT THE ENGINE LIGHT/OR JUST IGNORE IT? I DON'T KNOW WHO TO TRUST. I AM A WOMAN THAT IS RETIRED AND KNOWS NOTHING ABOUT ANY OF THIS. HELP

Dear mcshane1, I am actually surprised that you have experienced so many issues with your Thunderbird! They really are not bad cars from my experience, having been operating a Parts and Service Department at a Ford dealership when the cars were new, and for 7 years or so during their original lifespan. I am seriously concerned first that you get proper attention and more than one opinion going forward for any concerns you have. First answer is: Do not ignore your check engine light. It could be caused by many things, but ignoring it is just asking for more troubles. Based on your description of it coming on during acceleration, I am leaning towards a possible misfire situation, caused by a coil or coils, or spark plugs. Also, this engine has an issue where oil can leak out of the valve covers and onto the coil boots,, causing them to swell and start misfiring. It sounds like you may have had these gaskets replaced already -- so I wonder if you could get some assistance checking your Check Engine light at the place you had the gaskets replaced? They may find the concern to be related. Finding a good mechanic you can trust is really difficult, especially when you feel vulnerable. I am just alarmed, because aside from the oil leak issue I mentioned above, some removable hard top squeaks and rattles and water leaks -- these cars are typically very good. I've never experienced an air conditioner failure on a Thunderbird (or LS, the Lincoln version on the same chassis). I suppose things can happen, but...It just raises questions.
