2000 Lincoln Misfire

[Thorin John]

I have a 2000 Lincoln town car. The check engine light turned on and I took it in. I was told that there was a leak in the fill tube. I didn't fix it right away and then when the engine first starts it runs fine but after it heats up I get a little bit of a bucking (misfire). I got the fill tube fixed and the misfire began again right away. I took it back and they told me it was an intake manifold leak. Can that be right? Also is it possible that they never bled the gas line of the excess air or is that even a possibility?

Hello, I would start the engine and spray some carb cleaner around the intake and if you notice a smoother idle in a certain area, then yes it could be the intake. They usually crack right behind the alternator where the terminal is b/c of heat. As far as bleeding goes, I never heard of it. When I change my fuel filter, I cycle the key on and off a few times to build up fuel pressure and it runs rough until the air is out of the line. Same thing here. Maybe they didn't fix the leak..???

Just like Doctors and Attorneys,Technicans have a Lic to practice at your expense!

1) Is the problem misfire on the same cylinder or is it random?
