Re: engine codes what the....
What about the other questions? While some might sound silly they were
asked for a valid diagnostic reason.
For example the question "What does the exhaust smell like?".... if you said
it smells 'sweet' that might indicate you are burning antifreeze....
What we now know is you have an '01 4 liter with 67k, may have new standard
Autolite plugs and the old plug was some form of black.
Do I understand that it backfires also? How often?

Re: engine codes what the....
Sounds like you should run a compression check on the engine and compare
that cylinder to it's friends. If that one is low, good chance you have
a bad valve. If the compression is ok, replace the plug wire. Brand of
sparkplug is not critical, none of the name brands should die within weeks.

Re: engine codes what the....
So her are a few more ansewers to the questions:
spark plugs
dry black / they are champion brand.(new and old)
exhaust
the exhaust dosen't smell sweet it smells a little rich
We used a computer to pull the code the first time and we also earsed
it. today I earesed it by just un pluging the battery.
THe engine light has been on for about 2 to 3 months, but I didn't
worry about it it was running good. then all of sudden the light
started to flash why I was drivinh it and started to back fire. It
seems to idel ok but the bottom end wand why your on the gas, is
sluggish and back fires and spits. but full trottle it seams to run ok.
THanks for all the help you rule.let me know if there is anything else
you can think of.
