1999 Chevrolet Blazer
4.3L V6 Vortec
SES on.
OBDII codes = p0300 p0301
work done prior = fuel injector cleaner
Done to repair = plugs wires fuel filter
tech = kk
question = engine misfire Random cylinders 1 and 6
KK:
A common cause of misfires on this engine is sticking injectors. Injector cleaner
does not always work, if you are referring to an additive you put in the fuel tank.
The best way is to have a fuel injector cleaning service done. This is done by a
technician using a special pressurized cleaning system. This also is not 100%
cure, but much better than just adding a cleaner to the fuel tank. Of course this is
assuming there was no sign of the #1 and #6 plugs burning oil or coolant, which
will also give misfires.

Chevy Blazer Misfire Codes Random
2000 Chevy s-10 Engine size = 4.3 Vortec
Warning lights = yes codes = P1345.
Repairs: replaced plugs wires cap rotor distributor and still have correlation problem and
small misfire
Question = I am trying to get rid of this code but every time i try to clear it comes back
right away. I have replaced everything possible that i can think of that may have caused
the misfire, it all started with a misfire at id

Answer: it sounds like you are saying that you started with a
misfire, now after these parts were replaced, you now have
the misfire gone, but a code P1345. This is a common
problem when replacing the whole distributor. The
distributor is either not in the EXACT correct position, or
you need to do a "Crank - cam correlation relearn:" This
must be dine with a computer scan tool. First try and turn
the distributor a little one direction, clear codes, then go
back the other direction if code returns. These are very
temperamental. A VERY small adjustment will usually clear
this. If you cannot, you will need to do a relearn procedure
as stated above.
