Engine Mechanical problem
1996 Chevy Express V8 Two Wheel Drive 125000 miles
----------------------------------------------------------------
Hi,
This van had been sitting for a while,about 2 months.
It has always started before and ran good. I started it yesterday and ran it about a mile or two, it ran fine.
Parked for 20 min. or so, tried to start it and it turned over but would not start. I put a scanner on it and it read P0340(cam position sensor circuit malfunction) and P0157 (02 sensor bank 2 sensor 2).
I replaced the cam sensor, the crank sensor,dist. cap and rotor. It still wouldn't start, but after sitting over night started up. It ran for a while and idled good but when you put it in gear and hit the gas it has no power. Do you think one or both cat. converters are clogged, or could aan 02 sensor do this? Any help is appreciated.
