So I've found that the reason of my slow start up is a misfire in the 4th cylinder. I ran a compression test and the 4th is only pushing 30 PSI while the first is running 120 and second is pushing 95. (I didn't bother checking the 3rd bc the 4th is the obvious culprit) It's not the spark plugs or the coils. I'm thinking it can maybe be a worn valve or maybe a burned header. Is there a way to diagnose the actual problem without spending a ton of money fixing something that had nothing to do with the compression? Also I've never seemed to lose power. And I don't really notice the misfire unless I'm hitting 5-6k rpm on 4th gear or when I start up. (it's a little hesitant to start) Also the previous owner never got a valve job done and he had the car when it had about 95k miles and it currently sits at 135k would that be an obvious problem? I'm not too sure what kind of impact a valve job would have on it. Any help? Right now I'm kind of in the dark.
