Ethanol sucks! If ethanol has ruined the injectors on your pre-1996 car or truck, you too, will be replacing the injectors. My fine running classic Toyota started fouling plugs due to what I believe is a leaky injector. At $150.00 a piece for new ones, I opted to buy some rebuilt units but... DONT DO IT!!! Truth is, they did not work at all. I ended up putting the old ones back in temporarily and buying just one new injector. If you can pinpoint the offender, just replace the one injector but keep in mind, the rest will probably soon follow. If you have smallish hands, you do not have to remove the valve cover. When I took the rebuilt injectors back out and replaced them with the old ones, I did it with the valve cover on. Love on your classic and try not to feed it ethanol.
