The radio will cut out and come back on. Stop at a stop light the engine dies and show a p2074 code. After I replaced mao sensor tps sensor and ignition switch. The car would act like it has a miss fire in two cylinders. I pulled the cam sensor and found oil leaking on it. I am going to be replacing the cam sensor today.
I thought my cam position sensor seal was leaking but after closer inspection I found it to be a leak from the PCV valve which sits just above the CPS. I took the PCV valve out, cleaned everything well and applied a liquid sealer to the PCV and reinstalled. No problem since.
I have had our 2001 Dodge Neon for about 5 years and it's been pretty good however it has always had a small oil leak but unfortunately it has gotten worse, so to the point that I am forced to have the rear main seal replaced at 450.00 and while I am at it I am going to replace the valve cover gasket, because oil is getting on the spark plugs. In my option this is cheaper than buying a brand new car. I truly enjoy this little car as old as it may be.
