I just received a P0336 Cam Position Sensor Performance OBD2 code on my '98 Pontiac Grand Prix 3.8L K, what tools do I need to reset the timing?
While driving, attempting to pass another vehicle, the acceleration hesitated. I
tried acceleration a few more times afterward and the same thing was
happening, then soon after that the engine was chugging, or running rough,
acting like it was going to stall out. I parked it and checked all the spark plugs
for moisture to make sure it wasn't a gasket leak issue into the intake. No
moisture was found, so I polished the deposits off the plugs and re-installed
them. I haven't tried to turn it over yet since then. I would like to check the
timing while I'm in there, under the hood. Do I need a pully puller for this job? I
have most other common tools. What do I need to remove to get to the chain?
My block is still covered with old oil leaks oil, so it's not too clear if I need to
remove water pump or not 1st. I wish there was a timing mark on the belt pully
so finding Top Dead Center and making the alignment wouldn't be so difficult
or seemingly difficult. I mean, this would tell me right away to go deep.
The only picture I have right now is of the #6 (firing order, Left Bank near
firewall) spark plug. It had heavy dark brown deposits and two of the four ends
were closer to the insulator than normal where deposits may have started
Gap Bridging, leading to a dead cylinder or no fire. I did not receive any miss
fire codes, however I had a reading done as soon as I thought I may not make
it home. I do not know how long it takes for a fault to trigger a code.
