i changed the old spark plugs to new spark plugs and the old spark plugs from "cylinder" coil 2,4,5,6 has some black stuff on it not oil looks like rusty fire residue...spark plugs on coil 1, and 3 are good.
note: it smokes from the exhaust manifold "headers" and intake manifold "out".
also it the white smokes smells like coolant...
OK from where it is booming, there is a blue flame that comes out of intake manifold both holes the ICV and out through out the air intake.
==could it be the idle control valve...or could it be the timing?==
what could it be??!?!???
note:is the Idle Control Valve the same thing as the Fuel Injection Idle Speed Stabilizer...
(i was looking and saw these two items looks exactly the same!!?"
also the engine shakes but not a lot enough to feel it shaking a lot different from normal "not normal".
when i speed up engine is smooth until it chocks then it shakes and when not stepping on gas "it sits" it shakes.
please help me
