I've been looking through the threads and haven't come across my exact problem. Wondering what you all think it could be.
I just had the timing chain slip on my 97 blazer, after it was replaced, i have a total loss of power when you step on the gas. It idles fine, and moves a little. I've had it up to about 50 going down a slight decline, but if you push on the gas past a certain point, the engine slows, and if you push hard, it misfires a little. The first codes said it was the o2 sensors, which i replaced. (the left and right front ones) Now it still does the same thing, and the codes say low voltage on the o2 censors (131) (151). It also said it could be low fuel pressure, which was checked, and was ok.
I cleaned the maf sensor, replaced fuel filter, bank 1 and 2 number 1 o2 sensors.
Any other ideas of what it could be?
Thanks,
Del
