I have a stock 95 civic EX, and its been running like complete crap. Bad mpg, crappy idle and no power on acceleration. I pulled the spark plug in cylinder #3 and it doesnt smell like gas and has a black tip. the injector is engaging because I can hear it clicking. Does this mean its clogged or is something else wrong with the cylinder?

 

spark plug wires....on #3. Switch it out with #4 and see if the problem moves from one cylinder to the other.

 

I cant switch the wires. Each wire is just the right length to reach each cylinder.

 

Does cyl #3 have bright white spark?

Switch the injectors. Does the problem follow the injector?

 

get new plug wires. problem solved.

 

or make sure the connecter didnt slide up inside the wire. I had one come like that from the factory. Or even make sure its a good connection period

 

if you're not getting fuel to the cylinder, why does the spark plug wire matter? unless you're wording it wrong

 

opps...somebody mentioned plugs wires and I lost track. My bad

Try swapping injectors around and see if it moves.
