99 D2 w/ 4.6l shortblock and 4.0 ECU/top end.

I back down a hill on the trail yesterday, stop, put the truck in drive and it stalls. I make a joke over the radio about how I'd never heard of anyone killing an engine while shifting an automatic. Restart and and the CES light is on so I pull the code and found 10 of them. 3-4 I can usually narrow things down, but with 10 I'm a bit unsure as to what to try. Perhaps someone here has an idea.

p0102 - MAF - Low Input
p0134 - O2 sensor circuit no activity detected
p0135 - 02 Sensor heater circuit
p0154 - O2 Sensor circuit No Activity Detected
p0155 - O2 Sensor heater Circuit
p0161 - O2 Sensor Heater Circuit
p0340 - Camshaft Position Sensor "A" Circuit
P0445 - EVAP Emission System Purge Control Valve Circuit Shorted
P0448 - Evap Emission System Vent Control Circuit Shorted
P1884 - Manf specific

Since throwing the codes, the engine has hesitated when starting and is underpowered on the freeway.

I have an exhaust leak that is pretty big between the manifold and the Y pipe but that shouldn't have anything to do with these codes.

Craig hi
What fuse did you keep blowing? I was blowing an engine manegment fuse, had a hard time finding that the o2 sensor plug was bad. I have not blown a fuse in the last week so hope this was it. I did not throw any codes. 97 D1 5speed. Max

Mines a D2. It was Fuse F2. PCF, MAF, O2 sensors, etc are all powered by it.

The problem is back. I'm going to check the O2 sensor wire repair tomorrow to insure that it isn't shorting out again.

Well this thread saved me a lot of time. Spliced a new O2 in yesterday and BAM, 12 codes showed up this morning, all the ones above.
