I'm Awesome
I am really starting to wonder if someone may have at some point put a cam in my truck, I have a little annoying stumble at idle that comes and goes. We had my truck hooked up to a Genesis back a few weeks ago and the statement was made that my MAP was alittle low at around 9. To add to it I have absolutely no valve train rattle at almost 200k miles which is almost unheard of. Anything above idle and it runs like a top, I am getting 12.5-13 MPG mixed driving which is about right for my truck. I guess the only way to really know what is going on would be to pull it down and see what I have but that seems real counterproductive IMO. Would someone that was good at EFI live be able to tell something by reading the data?
