This morning, I pulled to a stop after driving
30 miles on the highway. There was a fast
ticking noise. I thought the timing chain was
making the noise like the tensioner was
not working. I have never heard this ticking
noise before today.

It immediately started running rough, and acting
like it was going to stall. I made it another
mile to my house and shut it off.

Then I changed the fuel filters hoping it was
an easy fix. The filters did not do anything.
There are no leaky fuel lines at the injectors.

It is smoking a lot now too since this started.
It's black smoke. When the engine is revved up,
the "miss" is not noticeable. The roughness is
most obvious when idling.

There was 1/4 tank of fuel when this started.
I just filled it up and it is the same.

Top speed is just 70mph. It used to be 80 mph
before this started today.

I am guessing that it has a bad injector.

Would a valve come out of adjustment that fast?
