Well i was driving my truck and it makes a pop noise then it rattles and wants to die. So i shut it off and it goes away a little but still have cel on. It seems like when i turn up the juice and run it hard a little bit it shoots these codes. Im stummped, i thought it was the lift pump so i installed the holley blue last night and it didnt do it all day until i got in it real hard from 3rd to 6th. Anyone know what the deal is? Maybe its the juice? Already been bak to them for problems!

 

Ive never ran the edge before but I just had the p0237 on my truck a couple of weeks ago, the truck lost alot of power, once I changed the map sensor it was fine.

 

I've had this code a few times and it seems to have gone away since I found that after changing my map, it still came up. When hooking programmers to the map, one of the pins pushed up thru the connector and was not making good contact. some thing this stupid and I drove it 100 miles to arthurdale,WV to Doug at Advance diesel and 30 seconds in he found it! I felt like an idiot after weeks of troubleshooting.
