Check engine light flashing
Sometimes when I gun it my check engine light starts
flashing and then I let off and within a few seconds it
stops flashing. I just had the plugs and wires changed and
oil change. It has 110,000 miles on it. Engine had a
ticking noise in it and I noticed it while it was idling. Took it
to the mechanic and they said it was a quart and a half
low on oil and they said this was the problem. After the oil
change I only heard ticklng one time. They said it was a
lifter not getting enough oil and now it's fine. Told me
they did not find the code from the check engine light
flashing but I don't know if I believe them or not. I'm
beginning to think they just wanted to do the work and
they knew that I would trade it in if I thought something
serious was wrong with it. Does anyone have an idea of
what's really wrong with my truck?
