Pull plugs....clean/dry plugs......re-install......disconnect injectors.....disconnect vac line from f/p regulator, and plug.......crank vehicle over several times.....now spray carb cleaner into intake as someone cranks car......does car run as long as you spray? Does it run without missing as you spray just enough to idle?

While I was out today, picked up ignition coil. Going to preform your test as soon as someone can come help. I will wait to install the new coil. If I get to it late or very early what is the spray test telling me? Depends on your answer, but should I go ahead and hook up new coil
