2005 Nissan Maxima 3.5 l
code: P0300

Car came in first with a p0301 and after finding out that the no. 1 cylinder was a bit black I dumped some mys oil overnight and cleaned up cylinder and is idling a way lot better than first came in. But there is a slight miss and getting a code p0300. I am now checking the fuel psi. and according to two different sources one is telling me 51 psi @ idle and the other is telling me 43 psi without vacuum and 34 with vacuum. Also i cannot accelerate rapidly as the engine want to bogg...especially exceeding over 45 mph. Help

Here is the fuel pressure specs....Fuel Pressure


Fuel pressure at idling Approximately 350 kPa (3.57 kg/sq.cm, 51 psi)
you might also check to see that it doesn't have water in the gas...I had one the other day had a multiple cylinder missfire and I put some HEET in the gas and the miss went away...Jim
