Nissan Maxima 2000. Intermittent problem, but frequent. Usually begins to happen once the car warms up, after 5-10 miles of driving, but recently I drove about 100 miles without any symptoms. The symptoms can be felt when pulling to a stop or pulling away. The car jerks rhythmically and at high frequency, which seems to correlate with engine speed. Once it gets above about 1.5K rpm the jerking goes away but there is a small loss of power. The car also idles at lower RPM than normal (~500rpm vs 750 rpm) and a bit rough. The only problem code that comes up is P0328, or 'knock sensor
- high' and it's not stored. Replacing fuel screen did not help. This started to happen recently and I've tried not to drive the car until I fix it.
The car has been fed only premium gas and synthetic oil since I bought it at 95K miles (currently 128K). All the ignition coils and spark plugs
were replaced about 10K miles ago after one started to fail. MAF sensor replaced 15K miles ago. The engine has been making clicking noise (not loud, only noticeable from the outside when idling) for a while now, before the problem I'm describing here first appeared. There's also small transmission leak - it's constantly wet but doesn't leave puddles. Also the fluid is at good levels (even above the normal range) and it's pinkish and clear.
It's the first time I'm using this website, so in case you need additional information, please email me [email protected]
. Also, I will pay if your answer diagnoses the problem correctly. I will try to fix it myself, unless it's something major like the timing chain.
