I have a 2001 gsr greddy turbo. Everything is stock. Ran the car so far for a year without problems. Two days aog te cel came on and it blinked a few times and then was constant. I pulled a code 72 and 73 misfire in cylinder 2 and 3. I reset the ecu but it pops right back up blinking then then constant. I changed out my spark plugs but the code is stil there after resetting ecu. What can be wrong?

 

check your compression. not to scare you, but mine started misfiring after my piston ring lands started cracking. or the blue box could be spazzing out...mine did that too...also greddy said that if you don't use their o-rings with the new injectors the seals might be compromised causing a misfire...but assuming it's been running well for a ywar it is probably not that.

good luck.

 

you would notice a fuel leak though.... i hope
