Hello HT,

I have a Honda Civic 1999 EX 5 speed manual transmission.

Last year my car wouldn't start so I replaced the starter. That fixed the problem at the time.

Thereafter my car on a coldstart (in any weather) shakes violently and misfires violently if I push the accelerator.

I replaced the rotor, dist. cap and wires. I do regular (synthetic) oil changes every 5k miles.

The only codes that readout are misfire cylinder 1,2,3,4 and random misfire.

I took it to the Honda dealer and they replaced my timing belt, my water pump and my cam and crank shaft seals. After that the problem went away until I took the car up to 100 mph. (I know the car isn't a performance vehicle , but it was the open road and I couldn't resist).

After the car gets up to operating temp the car ran fine. But now when I accelerate to higher speeds in any gears I get higher RPMs, but no more speed.

Today my car won't start. I am checking the main relay right now, but I'm looking for the root problem (the misfires). It's been a year of choppy running and I can't just give up I need to know!!!! haha

Sorry for the book

I pulled the back seat and removed the fuel pump panel. The fuel pump is engaging.

I pulled the main relay and there is nothing wrong with it. In fact it looks quite good.

I about to rip my hair out.

When were the spark plugs and fuel filter last replaced?

Have you resistance tested the coil?

Some auto part stores will test the ICM.

How is the battery, alternator?

I replaced the distributor in hopes of getting rid of all the misfires.

Unfortunately, I'm still not able to get the car to start.
The lights flicker when I try to turn it over.

The battery is less than a year old and all my electronics have power.
