runs rough and stalls

0130 is an oxygen sensor code. p0340 is your camshaft position sensor code p0336 is your crankshaft position sensor code

surprised it still runs....

go for the 02 may correct the other codes,its messin with the mine

thanks for the advise. I also need to change plugs, their worn out and plug wires, probably original. where is the crankshaft position sensor and camshaft position located and how hard are they to replace.
