deadlast said:still trying to give the car a tune up. changed the coil, coil wire, plug wires and cap and rotor. car still has difficulty starting up once in a while, so im thinking its my plugs. i took out the #5 plug briefly to lok at it, and it was coated a powdery white. also, while doing some exhaust work today, i saw my fuel filter was incredibly rusty, although it looked like very new lines and tubes. what affect can bad plugs and fuel filter cause?
RIO5.0 said:White plugs are kinda??? That would make me say it's lean, Tan is more the color you should be seeing....filter could help out there to since it sound ancient....alot times its not tho...but its cheap and worth changing if old to me...
Have you cleaned the MAF, check the timing when its warm, pulled any codes?
Hard starting can sometimes be an old fuelpump...causing excessive cranking before it lights off...
Pulling the codes may help to...you could have a sensor or the stator in the dizzy going South...they may have left codes behind??
Just some thoughts...

Just swap plugs and fuel filter and be done with it.
