So I am still having slight missed and sometimes cars tumbled or surges like. Also have a slight pinging at full throttle boost. Today I ran codes and an now getting code 28. Any ideas of best way to trouble shoot this. I cleared codes and ran back to back and code 28 comes right back. First I get a one twice for system pass then code 28. Thanks in advance

28-VAT out of range.
VAT is the temp sensor inside the VAM. It's not replaceable. I'd check wiring and if it's good then you need to replace the VAM to fix the VAT code.

So I found a broken vacuum line at vacuum tree. Seems to have fixed problem with this code. Driveover two hundred miles since fixed and no codes. Thanks
