Car had been running rough and stalling at stoplights. Check engine light came on as driving home. Stalled as parking, will cranks but will not start. Got scanner. Here are codes. P0030, p0135, p0300, p0446, p0451, p0461 and p2176.
Replaced O2 sensor. I have changed spark plugs as they needed it. Checked for spark at the plug. Tested fuel pressure at the rail, 57lbs. I was told by a friend that there should be 5V at the mass air flow sensor. I used voltmeter and get nothing. Any ideas where to look next?
