So here it is another problem, I was driving and came up to a stop light, all of sudden it felt like I was driving an earthquake. Immediately the Service engine soon light came on and made a quick turn to go home and check the codes, this is what I came up with.
1. P0150 O2 Sensor Malfunction Bank 2 Sensor 1
2. P0174 System too Lean Bank 2
3. P0306 Cylinder 6 Misfire
4. P1174 Manufacturer Control Fuel Air Metering
5. P0300 Random Multiple Cylunder Misfire

Where do I begin, mind you I have done extensive work on this already including All new 02 sensors (AUG '10) New Headgaskets (July '10) New MAF ( June '09) New spark plugs, wires and the ignition coils were replaced in (April '09).

Please Help I'm lost>.........

 

How much fuel was in the tank when this happened?

 

It had 3/4 of a tank in it, about a half hour earlier, i had just gotten back into town from work which is about 45miles away. but since this happened i have been drinking fuel like its been going out of style, i average 4mpg in the city, since then. Still shakes though only when idle, driving it, the heat gauge is fine as well as no shaking. Am i flooding my engine somehow? Or choking it of fuel when idle?

 

I am going to say it is a failing crank sensor.
The crank sensor controls the spark timing, when it fails you have no spark and the truck will not run.
It can set off mis fire codes when it starts to fail.

 

Whoops i forgot to add that, i just replaced that in October 2010. When the car heats up though it runs great, i see the problem consistenly on cold starts and very cold days where it would take 20mins to warm up.

 

You have a misfire on 6, wether it is the plug or wire, you'll have to figure that out. The 150 indicates the bank 2 sensor 1 has failed causing the 1174 and 174.
So replace the passenger front 02 take care of #6 misfire and all the other codes will go away.
Any questions, shout.

 

I did just have a chance to look at the connection and its wet with all of the blizzard snow we got here, could that have fried the sensor or shorted it out maybe? also lame question.... which of the plugs is for cylinder 6?

 

what kind of spark plug wires?

 

Water won't hurt the connections, but if you want to make sure nothing effects the connection, cleaner the contact and then use die electric on the connections, that will also stop oil from causing a problem.

 

I run with Magnecor wires, sounds good, i have a spare o2 sensor so i will clean and test that. Which cylinder is 6????
