Ok, so took the car out today its 1 degree outside. got the car to around 70 degrees, not fully warmed up (and i have retarded the ignition by about 7 degrees mechanically) and at around 2000 to 2500 rpm put my foot down in third. heard it pink and then stop pretty quick. tried again in many different gears at low rpm and high loads. it pinks for a second and then goes away. i can only assume this is the knock sensor kicking in and retarding the ignition electronically?
as the car got up to normal running 95 degrees ish. it didn't make a difference, still pinked the same. so it appears heat doesn't effect the pinking
my intercooler is the original one and is pretty covered in crud so there's probably not the best amount of air flow cooling the charged air (but it is 1 degree out at a stand still) probably minus 3 at 40mph though soon as i get a chance i will clean it all up and try again (cant see it making a difference though)
i also get a really loud more obvious pink for a split second just as i throttle off and change up a gear at around 4 to 5k. this i cant explain as there shouldnt be any load if im throttling off? or firing at all! im nearly 100 percent its pinking as its calmed down massively since retarding the ignition
i can only think its fuel related... ive just had my injectors cleaned. so possibly pump? or wrong chip for the mods?
I always thought the plugs looked a bit white, old ones and new ones. i will get some pictures up. going to run my tank down and thy some shell v power
sorry about a million questions. just want to get it running right. and would really appreciate any help
thank you all Taylor
