2003 GMC Sonoma Question: po141



, 2.2L 4 Cylinder, Devine, TX, June 20, 2010, 08:42

m.i.l. light is on. code scanned po141. Replaced o2 sens. cleared obc. came back on. same code. never ran the ethanol fuel in it. Could my cat.convert. be full o trash? I have to hit the key switch once, turn off, then turn it over to start. i put a fuel pump in it less than a year. engine idle surges @ start also. runs like a terd!?!?
