 Yeah. If you've already done the outside stuff, more than likely you've got – now, you need to verify it, though, because if you have a bad computer that's causing this, you want to fix that so you don't ruin the engine. Correct. But if you find out it truly does have lower compression in that one cylinder, find out where it is. Is it going past the piston rings into the block, into the crankcase, or is it going past an intake valve or an exhaust valve? When I'm working on an engine and an extended warranty company says, what is wrong with this engine? Well, it misses.
