·I have a 1995 Toyota Avalon that has a persistent miss, that according to
the Diagnostic Tool is P3040 (Misfire detected on cyclinder 4), I was
supplied this code from my local Advance Auto Parts Store. After not being
able to figure out, on my own, what was the problem with the cyclinder, I
took it to the Toyota dealership, the mechanic at the dealership seems to
think that the problem may be with the valve seal guides or a stick piston
ring in cyclinder four. The compression check on this cyclinder is much
lower than the other cyclinders. My guess is that the problem is the valve
guide seal, and the reason I think so is because sometimes after letting
the car set for a few hours and when it's started smoke comes from the
exhaust.
Anyone, what's your take on this issue?
