Is it more likely the timing or oxygen sensors?
my 2002 rav4 has 300,000 miles. It has developed a miss. I had the codes checked and
they are showing cylinder miss fires and sensor errors. If I hold the rpm's to about 2800-
3000 it smoothes out better.
Misfires are related to the coils and spark plugs. What are the code #'s?
