I've had this intermittent misfire for the past couple months, mostly only at idle . It's a Cylinder 7 Misfire. To diagnose I've put all new plugs in, swapped the cylinder 7 coil pack with cylinder 5, also reinstalled the old fuel injectors on the left bank cylinder. Still have cylinder 7 misfire. My next step is to do a pressure test.
After some research online, I'm scared that I've found the problem noted in this tsb: http://ww2.justanswer.com/uploads/ke...sb06-05-13.pdf
Been reading around different posts scattered across the web and many have posted it's a common issue.
If it is in fact a leak through the exhaust valve and I do have to replace the cylinder head, can I possibly do it in my garage at home without taking the engine out?
My main concern is the timing chain. I don't want to mess the timing up. I've been reading through Alldata and ChiltonDiy and looks like it's a big job.
