Forscan pulled some Codes, I have ?
Well I thought my truck was 100%, and I was going to installed a Chip. I decided to get my Forscan up and running to check and make sure.
The Buzz test Passed with no problems.
The cylinder contribution did not pass. I got error code P1464, which Forscan said that #8 failed. FYI, I turned the A/C on and the test failed. I ran it again with the A/C off and it failed again. I might have the wrong code
I then went to where you could select the gauges to view(PID's). And I saw where you could select all the cylinders injectors individually. I forgot what it was called, but all injectors were reading close to 0.0% at idle except for #8 it was reading 5.55% to 5.88%.
I am hoping this is good news, since I rather the injector be bad then a piston ring or valve.
I just got the Forscan and was wondering what other test or other things I could check to narrow the problem down before removing the Valve covers.
The truck runs great and there is no miss and it turns over smooth. No blowbye, just runs great. It is a 2000 F-350 dually with just over 202,000 miles

Do you have the grey CPS? If so it is normal for #8 to be out of whack when doing a cylinder contribution test. If the truck runs fine and there are no glaring issues I would not worry about it.
