alright guys my new car has been mis firing lately and its pissing me off, why becasue i can not cruise or drive slow. for my car muffler to sound nice an smooth i constanly have to smash the gas if i tap the gas a little it make a pa pa pa pa noise and sometime jerks all over the place. so far i change all the spark plugs, i change the fuel filter and i bought brand new spark plug wire to see if that was the problem but it wasnt, it wasstill misfring so i brought the plugs back and put my old one on.

also my friend has these NGK spark plug wire for an integra ls and i borrowed them to try on my car and when i put them on for some reason my car has ALOT more power and it sound deeper but it still misfires. and whenever i press the gas i can hear this knocking noise coming from the engine ( i have no idea what it is) So does anyone have any idea on what the problem could be? i only hear the knocking noise whenever i put the NGK wires on but when i have the factory wires it knock but it doesnt knock that loud or it not that noticable.

 

try the dizzy cap and rotor next

 

chk to make sure that all the injectors are working properly.. start the car, get a screwdriver, put the blade part on the injector and the handle in your ear,, all the inectors should make the same chicking noise ..

have you done a cylinder balance to see which cylinder is misfiring ?? chk engine lite on ??

 

no there is no check engine light on thats whats so funny about it. i think its dissconnected because, whenver i turn the key onto accessories mode on my other civic the check engine light would turn on well almost all the light turn on until i start the car than they would vanish. but i dont see any check engine light

 

In this case, you should take the car to AutoZone and have them use a scan tool to tell you whether any CEL codes have stored (free service).

 

Regarding the failure of your MIL/CEL to turn on at all, the picture may help you troubleshoot this important problem.
