Pulled the plugs, found 34p's. What problems can arise from those being in the motor? I get some mean pinging with a little more than 1/2 throttle and uphill inclines are always in 4th gear. Fuel pump pressure is within specs and filter is new. I need to jam some double plat's in there asap but throwing this thread out there to see if anyone has a take on it. Thanks
 
The 34's are the stock plug. Single p just means one conductor is platinum. I'm not sure if that would point to detonation or not.
