MISFIRE GM 3.5 PETROL

Post by onboardtech333 » Sat Jan 17, 2015 2:08 am

I am still very new to this pressure transducer testing and could use a little help on this one. Repeat cylinder misfire on cylinder 2 , saw what I believed to be a failing camshaft lobe or lifter and have now replaced both with these results. As a reference I have included a pattern from a known good identical engine. I know I'm staring at my problem but I'm too unsure of variables to this type of testing. Any and all help would be greatly appreciated , and will be reciprocated as best as possible.

Hello. Look at the schedule, I concluded that you have a problem with the exhaust valve.
Communicate through Google translator, sorry.
