It was raining too hard to do much under the hood. I hooked up my 'pro-scan' and read the most recent codes. P0300, P0303, P1316 and P1313.
I set up the ocilliscope to read out all 4 O2 sensors, while test driving it.
3 appear normal but the Bank 1 sensor 2 is a virtual 'FLATLINE'. Could a bad
O2sensor be causing the shuddering under acceleration???
