[V8] V8 not running well

[Ed Kellock]

A bad signal from the oxygen sensor could wreak havoc.
A failing rpm speed sensor can cause the engine to completely die.

What has been done so far (if anything) by any of these "mechanics"?

When was the last time:
-the oxygen sensor was replaced?
-the fuel filter was replaced?
-the air filter?


Did this start happening after a recent fill-up of gas?
Have you recently washed the engine?
Have you had any suspension work done that involved the tie rods?
Have you had any water leakage issues in the passenger side front footwell?

So far, the issue is rather vague and will require some clarification
in order to narrow down the possibilities.
