| Original Post:Click Here I have narrowed my miss down to cylinder 5 via power balance test. When removing the coil plug sometimes the revs don't dip at all and sometimes they dip a barely noticeable amount, but much less than the other cylinders. I also noticed the exhaust flow on passenger side is cooler than the driver's side and smells of gasoline. Great, so either an injector stuck open or a pinched O ring. Things I have done: -Swapped the injector twice with known good ones
-Used new O rings lubed with Vaseline to insert
-Swapped spark plug with known good one
-Swapped Coil Pack with known good one
-Swapped ECU with known good one All of this has made no difference in how it runs. With the injector unplugged from harness the smell of gas disappears from the exhaust. I'm at a loss. It as if the cylinder is not firing. But I have checked everything I can think of.
