Like the title says, I have a 2000 civic si (125,000). Within the last 5,000-10,000 it has not been running right. Approx. 10,000 miles ago, the check engine light came on and the car was running really rough. I took it to AutoZone for the free diagnostic and they said cylinder 2 was miss firing. I replaced distributor cap, rotor, all four injectors and fuel filter and still a check engine light. Then one day I was driving it and the light went off (problem solved). Since then, the light has come on several more times and it was fixed with a bottle of fuel injection cleaner. A couple of days ago, the light came on again, and this time it's flashing. Cylinder two is not getting any fuel. I spoke with Honda and they said I need a A12 ecu, well my car has one already.............so I'm stuck, what do I do, any ideas, anyone ever had this type of problem?

 

anyone????????????

 

So have your checked yourself to see if its getting fuel or no??

Try a friends ecu???

I think thats what they are telling you.. is that your ecu is bad...

 

give me the ECU error code and we'll go from there...

 

i'll get it tommorrow

 

It runs rough and when i disconnet #2 injector, it doesn't change at all

 

for clarification, the dealership thought I had the A11 ECU and I needed an A12, but I have an A12. Autozone did another check today,
cylinder 1 and 2 misfire

 

What did you plugs look like? Might wanna try replacing them?

X2 on the bad ECU part. I just had one go out in my car..

+2

As you already have a new cap and rotor, your next attempt at solving the misfire problem should be to replace the plugs and wires.

 

plugs and wires have both been replaced...........

 

try a compression could be bad rings i had same problem misfired in every cylinder

 

did a compression test, #2 cylinder is at 50-60.........................where do I go from here?

go to the bank and make a withdrawl.........................you are about to need it. those numbers are and you need to find the cause. good luck bro

 

like what he said make a large withdrawl and start taking it apart im guessing fried cylinder torched the rings loss on compression and causeing to miss i had same problem only mine was all 4 and number 2 had 0 compression.

 

it's in the shop getting a b18c, thanks for everyone's help.
