Hi! I have an 03 Accord LX with a P0339 code (replaced crank sensor). The car has a long crank and I have to pump the gas to get it to start. Once running, the car surges on idle but will run beautifully once I start driving. While driving the car will act as though it is red lining once the tach hits 3k rpm. It also reads on the scan tool 7k rpm when key is on and engine is off. Anyone seen this before? I'm really upset with the dealership I took it to because they are saying I have a misfire on 2 cylinders. I drove it there with no issues and would know if my 4 cylinder engine is missing on 2. Please advise!
