Having a bad shake but only at idle - but it shakes pretty bad. I have codes coming up of - 0174, P1131, and P1405, but I just can't keep guessing at what it might be. Could this be as simple as a MAF cleaning, a pinch vac line from installing the fuel tank, . Any help would be great! I want my Baby to surpass the 250,000 mark without being pulled behind a tow truck to do it!

Hi
Lets start with P1405 DPF-EGR sensorupstream hose OFF or PLUGED see diagram. P1131 HO2S lean and P0174 System to lean bank 2 can be caused by EGR malfunction. So that's where you start.
Let me know
Thanks for donate

Of course the one piece I didn't just get on my lunch break! Ha! I am also going to clean the MAF sensor since I just bought some cleaner, I'll probably do all plugs while I'm under the hood. I did check on that part while I was there and they hav it, so I'll pick it up after work and let you know what happens. Thanks again - will be back again soon I'm sure!
