My 95 Maxima misses badly when you stomp on it. It seems to run fine
otherwise. The check engine light is on and is giving a PO340 code. The car
has been in a Nissan repair shop to try to correct the problem. They
replaced the cam position sensor. Inspected wiring from sensor to pcm. Ran
new wire from sensor to pcm. Changed pcm (installed used one temporarily)
Nothing has helped the problem.
Here is the kicker! The car was in a different shop, (not a Nissan shop)
about 5 weeks ago to have the water pump replaced. My wife drives the car
most of the time and she didn't notice a problem at first. She cannot
positively remember if it ever missed before the water pump replacement.
I made the Nissan service manager aware of the water pump replacement and
my suspicion of a possible connection to the miss when I first took it in.
At this point they say It could be the timing or a chip in a tooth or gear
and that the next step would to pull the engine to check as they cannot
eliminate the timing issue completely with the engine in the car.
Any suggestion or comments appreciated.
Thanks
