Codes, codes, codes
Ok, so I got my Auto Enginuity yesterday, and did some motoring of the truck with it both hot yesterday and cold this morning. hot or cold shes kicking the same codes.
P1316 IDM Codes Detected, then when I do a buzz test I get P1271 Cyl #1 High to Low side open, P1272 Cyl #2 High to Low side open and P1274 Cyl #4 High to Low side open. these need to be replaced I am assuming since the UVC's and VC Gaskets are less than 4 years old.
Any input on them? Also, are these 3 the IDM codes the DTC's re talking about?
