Plugs read fine, just changed them recently and all were nice and tan,
right rear a lil more crusty than the others, but color still good and
all were dry.
Yes there was one other symptom, but I thought unrelated: After car
sits for many hours (over night or in work parking lot), regardless if
outside temp is 50f or 90f,..... it coughs and sputters for about 3
city blocks, then clears up and runs near perfect. Very slight ruff
idle at stoplites after warmup, but absolutely no cough or sputter.
Does the cough and sputter thing every single time (after the long sit
only), and ALWAYS clears up within 3 citi blocks.
