Re: 04 Blazer runs great till it warms up then dies
Also, I have changed all 3 02 sensors, Catylitic converter, vacuum box behind drivers side rear wheel, MAF sensor.
Question: is there a vacuum hose that goes down to the transmission? It is throwing a pending code of 131 and 151 low 02 sensor reading. but its not bad enough to turn the check engine light on.
