I know what this code is. Its multiple cylinder misfire. I was wondering if this would be caused due to running to rich?

 

do you have a 6 bolt engine?

 

no its a 7

 

The misfire only happens after I hit boost. This damn misfire is aggervating man.

 

Im gonna change the plug wires already changed my plugs. If it aint the wires I guess I will try the crank trigger sensor. And if that is the problem then I will check for CW.

 

Coil pack/power transistor/ boost leaks/ running rich... lots of things to check.

 

Fixed boost leaks did have one but not anymore. Still have problem. Am on the rich side of things thou. have a greddy p/h wideband heard they were not accurate thou. But it says my a/f pegs at 8:1 which is rich as hell. But plugs tell me other wise. With white on them. showing a lean or high cyclinder temps. Im running 1.2 bars until i get this problem right. And im using the ngk br7`s. have 650 inj on a 16g.

 

i got a buddy who threw that throw plugs in that run hotter

 

i had a misfire problem and my o2 sensor was f'd the wires had shorted out.. my air/fuel was saying rich meanwhile the wideband was saying lean.. so the ecu saw rich and tried leaning out the car.... u should be getting another code if your running too rich or too lean.. but then again u may have to drive hard b4 that happens and your gettin mis fire too soon...

 

po300 is a random misfire if you did boost leak test and tested fine i will go with factory plugs and wires not discount factory if that doesnt work try cam sensor had a customer with a bad 2g cam sensor if you want just call me 813-843-7876 this is not dario this is the brothers
