This does not seem possible but it is happening. 1999 EB 2WD V8 49000k
I get about 18mpg and the truck runs good other than the idle miss.
New IAC, DPFE, TPS, Fuel/Air Filter, Plugs/Wires and the Fuel Pump. Cleaned the MAS. Ran Injector cleaner, swapped gas grades and types.
What I have discovered is when I have a full tank of gas the idle miss is
75% gone, as I get lower on petro the miss is more noticeable. I have ran three tests now in the last couple weeks, everytime the same, full tank less miss.
What the heck is going on, I cannot figure out why this is going on.
1 more question,
I cannot find anybody with a V8 to compare. My injectors click very loud, I have used a stethoscope to be sure it is not the lifters. The injectors really click up a storm. Is this normal??????????
Thanks, Sonny
