I have an 05 SD with a Magnason Supercharger installed. (102000 miles now) For the first 2 years and 35000 miles all worked flawlessly but now it is starting to act up regularly and I cant get my finger on the issue. I am getting code alarms for lean readings on multiple fronts p0171 p0151 p0174 p0001 I Have replaced all 4 of the o2 sensors and all was good for 1 month but back to 2xper day having to clear the alarms I have used up 2 full cans of ether trying to locate a vacuum leak but nothing was found at this point I am going to replace the intake gaskets and get a replacement CPU (off ebay-with exchange) and try that. Any suggestions or other ideas?????
