Hey guys trying to fix my 94 civic hatch
Replaced most parts and still am coming up clueless to what the problem is with my car
This is the list of parts that I've replaced trying to trace the issue
Brand-new distributor, brand-new coil, brand-new ICM, plugs wires cap and rotor fuel pump fuel filter main relay
cleaned and checked all of my grounds on the car
And even swapped another ecu

The car has 104,000 miles does not smoke burn oil or leak

There's no check engine light,

So here are the symptoms that the car is doing

First coldstart idles perfect and as the idle comes down it gets a little rough has sort of a cough every 5 to 10 seconds

When you drive the car at low rpm's between 2000 and 3000 at 50% throttle roughly it will have a stutter like no power once you ease off the throttle a little bit it starts to climb as normal then boom the coil pops every time like clockwork nothing else is harmed

I had a few people tell me that it is a burnt valve could this be it? Please help me diagnose this problem it is Driving me nuts and I really don't want to replace the motor

Or if anyone is in the Waterberry Connecticut area to come down and maybe tell me what it is or check it out let me know

What do you mean by "the coil pops"?

polodinks

Blowing the coil meaning it's fried no burn smell but replaced the coil and starts right up again

I may try another ecu in a few days and also I just cleaned up my grounds never left my driveway cause I'm worried I will blow the coil again and I'm out of coils

Former User

I'll be the devil's advocate. Tell me something that proves the coils actually blew rather than there's an intermittent other problem.

I'm not sure what you mean tell you something that proves they blew out....
Driving home with the car I made it maybe 2 miles in the car just shut off I pushed it into a parking lot car would not start at all just kept turning and turning swapped out another coil from my other civic started right up and made it two blocks before it blew the coil again not getting any spark

I know there's another problem a electrical problem somewhere
Not sure where it is or what it is.....
Hoping someone had the same issues or same problem and diagnosed it

This is not my first civic i've had many Hondas and Acuras had similar problems but not like this just trying to explain what the car is doing and hoping somebody can narrow down the problem for me since I replace all the parts that I thought could be wrong or broken or just used with age and wear

We need you to verify that the coil is "pop". Instead of just replacing them, get a mulltimeter and show us some readings.

If you can verify the coils are actually bad, then open the distributor and check whether the inner cover is missing.

Another common cause for blowing coils is that the high voltage inside the coil can't find proper ground through the rotor, distributor cap, plug wires, or plugs. Doing an ignition system tune up where these parts are replaced with OEM ones will generally solve the problem.
