My check engine light went on Yesterday. I went to Autozone and the code checked out to:
P0155 - 02 SENSOR CIRCUIT MALFUNCTION (BANK 2 SENSOR 1)
Is this one of those things that might be "a loose screw or wire" or is there more to it?
On a related note, I have noticed that if I let of the gas and the car idles down to below 2000 rpm, then the car accelerates in a herky jerky motion when I step back on the gas up to about 3000rpm. Is this normal or maybe even related to the above problem?
