Most likely your O2 sensor or possibly a vacuum leak.There's a TSB for the 2006 Toyota Matrix 1ZZFE, same as the Vibe. Here it is:Component Description:12. ENGINE AND ENGINE COOLING Bulletin Number: 05105 Bulletin Date: Nov 2005 Vehicle: 2,006 Toyota Matrix Summary:MALFUNCTION INDICATOR LAMP ON WITH DIAGNOSTIC TROUBLE CODE P0171 OR P2195. ( NHTSA ITEM NUMBER - 10018290 )

Raven thanks for the reply I have not investigated the tsb yet but will. I clean the mafs and i changed the pcv valve. I also changed the spark plugs and they were toast. the cel came back on and i ran the codes the only code was the po134( a dead o2 sensor at bank 1 sensor 1) I am going to order a sng sensor and i think that will take care of the issue ill keep you posted

Are O2 sensors covered by the longer emissions warranties?

[Tonebalone]

Those should be covered by the 80K mi. emission warranty.

I ordered the part last week and just recieved my SNG o2 sensor $78 I installed it in 15 minutes. I cleared the codes and have driven around a little so far so good I will post again if anything changes
