i have a 99 ex and i keep on gettig these codes. they are for misfiring in the cylinders. i just adjusted my timing and it went away but then it came back, what could be causing it? could my timing belt be going?

What condition are your spark plugs in?


Maybe that would be part of the problem?

did you change the wires recently and screw up the firing order?

i haven't messed with the plug wires anytime recently. maybe i'll try new plugs before i go changing the timing belt.

Is this a bone stock 99 Ex?

Have a turbo kit - maybe the GReddy kit with the bluebox?

jeffsciv23

it had a t-25 but i sold that kit and pieced together a kit with a t3. not the bluebox but i am running a Vafc hack.

What is your base timing set to? Did you verify it with a timing light?

Did you run the Hack on the old T25 setup? Did you have the same misfire problems?
