i have a 2006 VW Jetta with 92K miles and just a couple of days ago my check engine late came on and when i took to an auto store to check the code, it came as P0332, Knock sensor 2 in bank 2 is faulty. Three things have happened all around the same time and I am not sure if they are related and are just coincidence.
1.Check engine light came on.
2. I have noticed after that, my car RPM has dropped, idles at about 600-700RPM and when trying to accelerate, it tops at 3000 RPm and feels like the motor cuts off at that point and I have to step off the gas and the car runs ok again, but cant go over 3000. had trouble getting on the interstate due to this and thought the car was going to stall, but it didnt. just had to back off the gas and let it run, It did go up to the speed that I wanted, but seems like it wont go past the 3000 RPM point.
3. My fuel gauge, drops to empty when it reaches the half way mark on the meter. It stays at the correct level when I start and keep the car in idle, but when I start moving, it drops to empty. When I fill up the tank, it goes all the way to F, and after the car goes the usualy of abt 190-210 miles, when It reaches the half full level, teh meter drops to zero, so have been using my trip odometer to drive after that.
any ideas solutions? is it safe to drive? what is wrong and what is the fix? how much would the cost and expense run? should I take it to a VW dealership for the service? can my local mechanic be able to fix it?
