i just got done failing my emmision test and i naoticed that when they were do ing the part where they run the engine at 2500 rpm it had a miss firing. it just kept popping. what could this be and how can i correct it?
thanks
Nate

 

hmmm well..........


poping is normal at idle but I have never heard of a rotary poping while it was running a 2500rpm constantly. I would suggest cleaning the injectors and redlineing it a couple of times to clean all four injectors

replace fuel filter and check timming
