I suspect that at times I'm not running on all cylinders. Its hard to tell, though. The motor sounds about the same regarding its "throatiness." But there seems to be a reduction in power - particularly noticeable when trying to accelerate up a hill in 3rd.
Can someone tell me the process for testing? Do I pull over, keep the motor running and pull and replace the sparkplug wires one at a time to listen for an engine sound change? Is there a shock potential here or is that spinning fanbelt my biggest worry?
Thanks in advance,
