Thanks I'll go to Napa. How about a timing light. I didn't take a video yet but soon. I'm still on the road . Before I left was able to crack injector lines and each one made a difference. Retarded timing and it sounded better. Vibration changed a bit. So compression and timing test is next. Oh...
Thanks for the help. I will check injectors and compression first and go from there. I sure appreciate your knowledge. I'm an OTR truck driver and will be back in a few weeks to get it done.
