Welcome to Engine Performance. What if.... What if your car is idling rough? Would you
need a set of spark plugs? Maybe a carburetor adjustment? Today's cars are very
sophisticated and sometimes the most simple complaints turn into complex diagnosis. Or
sometimes the worst complaints are the easiest to repair.
In the above example perhaps the oxygen sensor wire has touched a hot piece of metal
and burned into, at that point the computer would not get it's "input" and would
most likely substitute a valve for the failed part, this could cause a rough idle.
The engine performance section is perhaps the most challenging part are for a
technician. However it is equally as rewarding.
