Those Who are Wiser than I-- Problem once again with 4ks...Changed wires, rotor, cap, and plugs...all Bosch. Plugs are WR7DC and gapped at 28. Still stumbles a little at start but when I took her on the road in 4th at 50+/- mph the tach went weird. What did I do wrong now? TIA Ron ps-I put wires on where they came off. *****Ron Roth Ithaca NY USA 84 4ks*****
