Noticed that my o2,s have been a little inconsistant lately took car out to check boost and fule pressure was getting small amounts of knock lately every so often. pump good base fule pressure 44 wide open with 20 lbs boost 65 lbs.
Holds pump good and o2,s were 843 no knock get movement on scanmaster but at idle they are normally at 395 to 410 jumps around. thought should move up n down more 200's 300's 500's ect my o2 sensor is about 14" away from turbo on down pipe. changed o2 sensor and seems to be about same smells a little fuley
hit gas peddle a few times noticed got some minor knock in drive way in park not hard on peddle either also running autolite iridum plugs thinking of going back to AC Delco cr43ts should this help or are there other things I can look at just cannot figure this out some times can get on car just screams other times get into it and start geting knock so i get out of it. Need as mutch input as posible please can sombody help. Also run 50/50 93 and 110 race gas.
Thanks
Tom
