Brief Setup - I was driving down the interstate. Doing a little over 70mph. The car made a short lurch like it was blocked up. Then things were fine. Not long after that, my Ultra Guage showed 15 codes and my CEL came on.

SIDE NOTE: My Ultra Guage stopped measuring current MPG and average MPG right after the "lurch".

I made a list of all the codes, some of which are o2 sensor related so I'm not sure if those are/could be triggered by the other problems.

To get the full idea of what happened I'm going to give you ALL the codes that triggered. I researched them already, but I want to see what you guys think.

My biggest question is once I figure out what these are, can I do the repair myself? I'm not a mechanic, but I have replaced the upper IM gasket, coil packs, wires and plugs on my own so I'm capable of doing more complicated repairs.

Here are the codes:

P1451

P0414

P0445

P0448

P0102

P0340

P0134

P0135

P0154

P0155

P0141

P0161

P0159

P1884

P1482


There are a couple of pending codes, but they all relate to the O2 sensors so that's the least of my worries.

 

Could be just a loose connection of a tube of plug or harness around your SAI if you have it.

 

Best thing to do is write down the cods, which you have done, check for obvious problems like loose battery cable connections, then I would clear the faults and keep driving it like you normally would and see if any of the same faults come back.

 

Did you happen to fill the truck up with gas in the 24hrs prior to this happening?

 

I may have put some gas into it, but I don't think I filled it up. Premium near my house is $2.10. Premium near work is $3.30. I never fill up near work.

One thought went to the gas cap, but I made sure it clicked several times when I filled up this morning.

I do have SAI so I will look it over tonight once I get home and the engine is cooled.

 

My thoughts as well

Do me a favor...Take your gas cap off and clean it as well as the spout with some scotch brite. Clear the codes and see if they come back.

I was a person that was getting codes similar to the ones you posted AND after cleaning my cap and spout, they never came back.

Worst case scenario, you spend 5 minutes and $2.00 on something that doesn't work
