i took out my car today, same settings as ussual. i recirculated the bov yesterday. but today in 3rd gear it started hesitating/ missing. i lost power so i let off imediatly. almost felt like the missing for the po300 code, but i was wot. the afr read 11.0 at leanest. i pulled a plug and it looked whitish/grey. shouldnt it be blacker with more soot at 11.0 afr? i am running a wideband. my fuel system is built with 880s, i was running 12.8 psi when the stubble occured. any thoughts on what i should do, check, or change?

 

bump, anyone?

 

stock plugs..? i switch to some NGK colder plug and it did what u describe..got new iridium plugs and it was fine again..

oh and the top should not be white...should be alittle brown, and the base should be kinda black...

 

i had hgk a step colder, then switched to the stock heat range. both show up a whiteish on the electrode, and dark black on base, no melting or build-up. wait, is the electrode the little node surrounded by the porclin (sp?)? is the very top part the ground? im confused on the terminology. its the top part that is whitish.

 

sounds like a head gasket i went through the same thing

 

didnt read the 12.x psi part, dont know...

 

i meant 20.8 psi. i dont htink i blew a head gasket. no smoke out exhaust... except dark gas-rich smoke at beginning of rpm band. what are charactersistics of blown head gasket? i heard a raw egg smell. white smoke out exhaust.
