Did you check the valves to see that they are opening and that there are no broken valve springs ?

My "Hiccups"

I have not checked the valves yet. I'm waiting on a buddy to bring me his tester. The fuel pressure tested fine, so I'm hoping I'll get some kind of answer about the valves. It has been WAY too hot here in CA to even think about working on a vehicle. Thanks for responding. I'll post an update. Enjoy the weekend! Safety First! Thumbs up
