i keep getting code 73. i replaced the plugs and still get a code 73. what to do.

 

I like your post trailer, f-nascar, f-civics, and f-n\a. anyways, on my 12psi gsr I am constently geting 71,72,73,+74 codes wich are missfire codes. try these options is this order: decrese the plug gap, change the plugs out for some ngk non-projected nose copper plugs(heat range 7), slightly advance timing(trust me), buy a msd 6a, or if all else fails sell the car.

 

yeah i bought the ngk brpes somthing. are those the ones to get. i gt a 73 constatnly. and at times the engine light flases instead of staying on.

 

u are actually leaning bro...try richen up the fuel a little bit or invest on some fuel pump...i used to have the same problem with greddy kit and all i did is put som fuel pump and the random misfire never came back...random misfire can be anything an dit can be something serious too..so pay close attention to this matter.

 

does is gives you the CEL at idle, vacuum or what ?
I had all 4 cylinders misfires before at idle, and it turns out that the FMU was bad, it stick open dumping too much fuel at idle...

check your plug gap, and for once, reset the battery, bypass the fmu and leave it on idle and see if it still bogged...

well i got it at idle. only on cyl 3 though. i have a s-afc and im running 10% more on all rpm's. any ideas?

 

did you try by-passing the FMU like I said earlier...

That's how I found out about mine..
