I have a 97 Honda civic an ive been having the same problem over an over an cant figure out whats going on. the car is running like crap an getting terrible gas mileage, all cylinders are firing except cylinder 4. ive replaced all wires, sparks plugs, dis cap, mass air flow sensor, took the injectors out an cleaned them, an the car is still not firing on cylinder, please help.

 

check compression, fuel pressure, possible clogged injector as well

 

How do you know it's #4 ?

 

This is the accord section also....Do civics come with mass air flow sensors?? I dont think so!?

 

misfire code stored? CEL on?

 

we hooked up a timing light to all the wires an the only one that didn't have fire was cylinder 4
