Thanks,I was very carefull marking the points I welded with a degree wheel.I may be out a bit though.I'm thinking I'll see after injectors how it works.Is there a heavier fluid I can use? and how much extra can I run.The truck has never been so nice to drive since I bought it,no shake at idle and the clutch very smooth,I'm thinking possibly I'm getting a vibration or miss from a faulty injector.
Thanks for the info
