Ford ThunderBirdFord thought they'd take their own stab at the nostalgia business. There are quite a few last-century icons that wear the blue oval. For a revival subject, why not use a car famous enough to have been the subject of Beach Boys songs, starred in George Lucas movies, and has been gone long enough to be missed? Why not indeed. In 2002, the Thunderbird was reborn.
I'm thinking I may need to take my t-bird to a garage, and have a real diagnostic computer hooked up to it. That may be your next step, but if you want to still try a llittle more troubleshooting, you can check to see if the injector #5 is getting the command to open.
how to check for power to injectors
A noid light is a small incandescent bulb in a socket with pins that plug directly into the wiring harness leading to your fuel injectors.

Ok, On cylinder #5. I swapped in another plug, and plug wire, reset code. After 20min, still misfire on cylinder #5. One thing i did notice, when i removed the plug from cylinder # 5. Plug was black, like it had been powdered coated black. It was wet like it had been oiled, but the tip & electrode looked as if they had been powder coated flat black. Does this mean, no fuel or no spark? I guess today, I will have to pay to take it and have it put on a computer. I'm begining to wonder if Autozone's reader is leading me astray? The car does have a miss, but it doesn't feel like the cylinder is completely dead.Any ideas???
I think the computer actually pulls one wire to ground, to make it fire. I found a guy that would hook my t-bird up to his computer for $40.00. So, maybe thats my next step.

It would mean your getting fuel but no fire, a "dead cylinder". You have a V-7 engine right now...

my service light is coming on now but idk whats wrong with it and after a while the light goes off but then when i restart my car it comes back on should i get this checked out by someone or should i not worry about it?
Do you have a distributor and coil in there, or do you have coil packs?
IF you have coil packs, you can try switching them and see if the missfire moves with the coil.
YOu can also do some checking with an ohm meter.
Here is the method, but you'll have to get the values for your coils.
Of course since you'll have two of them you can compare the values that you get for the good one to the one that may be bad. If they are significantly different then you can suspect that bad one is actually bad.

Yep, I swapped coil packs left to right and the problem stayed on #5 cylinder. So now, I'm at a loss. Somebody mentioned possibly a stopped up fuel rail? Could the rail be stopped up so #5 doesn't get any fuel, but #6,7,8 do have fuel? At this point, I'm lost for idea's. I was taking it to have it put on a machine yesterday, but when i got there.... the shop was already closed for the day. Am I missing anything here? The only clue I have, is the fact that the new plug, was black with carbon, like it had been powder-coated flat black. Any idea's or suggestions? So far, I have installed new plugs and plug wires, new fuel injector, a second plug and plug wire, on cylinder #5, swapped coil packs... I reset the code each time, but still the reader at autozone says... misfire cylinder #5. I consider myself a pretty decent mechanic....This is really hurting my pride.... lol

AS you know, you need air fuel and ignition (spark) and compression.
Did you check compression?

UPDATE!!
Hey guys paid $60.00 for a professional diagnois. Electrical system is working properly, 60,000 volt at spark, fuel injector is passing fuel properly. Guy that owns the diagnois center believes the exhaust valve is not opening on cylinder #5, resulting in mis-fire of cylinder #5. he says, the lobes on the camshafts are pressed on, and believes the cam shaft lobe has either slipped, or move completely off to the side, so vlave is not moving... sounds bad. Has anybody ever heard of this? I am taking the motor to a mechanic tomorrow, to have him pull the valve cover and check to see if the exhaust valve is the problem. At this point, not sure if the motor is worth repairing, or should i be looking for a replacement 4.6 motor? IS a bad cam shaft a terminal condition? May be cheaper to change out the motor? What do you guys think??
