I have been experiencing moderate to heavy shake at idol, I recently ran injector cleaner through and cleaned and gapped all the plugs and it only seems to have gotten worse (not necessarily due to the work). It also sometimes starts like it is going to choke out until I give it some more gas, fuel filter was replaced 8-10k ago. I have 75k on it. Is it likely the wires or should I check into something else? Ideas PLEASE.
