for example.
I have a 07 Avalanche ....I want to tune it ..turn off dod ...buttt!!! I have some issues its idling really rough
Ive done head gaskets on this thing I replaced oil pump and timing chain it has 225000 miles on it
Im just trying to keep it doctored till I can build a new engine for her
I would have loved to change the cam and did dod delete kit
I have a scanner tool ...a cheap one from auto zone it says misfire detected but it wont tell you what cylinder it is
will the hp scan tool show me what cylinder or cylinders are miss firing
I think just playing with the tune will improve the way its running it idles really low
at speed it runs pretty good
