2005 Yukon Missing on Cyl
My 2005 Yukon has been missing on cylinder 7 for quite some time.
Strangely it seemed to start just after I replaced the fuel pump last year.
I did the following and after each still got code for misfire on #7
1. Changed all plugs
2. Swapped #5 and #7 plug/reset code/same code came back
3. Swapped #5 and #t coil/reset code/same code came back
What next?
