Did it just happen all of the sudden? We need more info/background story about the car. Stock, engine code, swap, wiring?

Someone move this to the correct forum.

You've all been had.

Original poster: check the 92-00 civic section. In the top area they have a thread on check engine lights (CELs). Check what your codes mean. Then fix.

Sorry what section do I go to and how I am new at this

OP i moved this to the appropriate section, 92-00 honda civic. you were in the section for the honda s2000.

Former User

You have a bad case of random misfires on all four cylinders. Start by checking/replacing the spark plugs, wires, cap, and rotor. And if the fuel filter is old, also replace it.

sanchg3

I just replace the cap and router fuel filter is new all so replace the fuel injecter modulater I tried staring the yestreday and know it won't even stared up help

OP where are you located.

Former User

What about the spark plugs and plug wires?

If those are fine, then test the coil and have an auto parts store test the ICM for you.

sanchg3

My wires r new and I will test the icm I willing to try anything about know I am located in California

Former User

What about the spark plugs? Have you inspected them? Are they properly gapped? What brand are you using?

Former User

What is this? Is the engine modified or stock?

sanchg3

The engine is stock and I am using Bosch plugs

devney

Switch to NGK's.

Jimster480

while he should probably switch to NGK's. I doubt this is his problem.

Former User

I would do this^, and then go from there.

sanchg3

ok i will check my coil and my icm and change my plugs to ngk,s i will get back to u

sanchg3

Ok just the icm and the coil and they both pass but still won't start
