07 Silverado rough idle and missing
Hello, I am having some issues with my 07 Silverado. It has 114k miles and I changed the plugs at 100k miles. When idliling, the tach with bounce about 500rpm and run rough. Also when driving I've noticed that when accelerating it will miss, but when I let off the pedal, it smooths out. It'* not a constant issue, but seems to come and go. I've tried see foam through the tank to see if it was a dirty injector. Thank you.
