Answer 1

This is usually a corrosion problem somewhere in your set of plug wires. The easiest thing to do is to remove the wire ends one at a time from each end and inspect for corrosion or burnt insulators. The cap and spark plugs should be inspected and replaced if nec as well. Also check the coil to dist. wire for the same thing. Good luck.

Answer 2

Try changing your fuel filter and air filter they could be clogged or their could be a leak in your fuel system and if that does not work than have a mechanic check your fuel pump. If your fuel injectors are not getting the right amount of pressure than they will not be able to keep up with the fuel demands of the engine.

Answer 3

if you have a volt meter check the middle wire on your throttle position sensor that is located on the passenger side of the air intake if that reads anywear between .04 to .05 at full throttle then it's good if not then it's then it can be adjjusted to so, also move it up and down slowly and check for any sudden fluxuations in the voltage that is a indication of a bad one

Answer 4

Does sound like your plugs and wired are fouled. Replace both, being sure you set the correct gap on the plugs.
