ok the other day i was getting on my car and then wen i pulled up to a red light it sounded like my block was kknocking . today i started her up and it was just idleing rough and it misfires till about 3 rpms . i changed everything spark i think its a fuel problem can any1 help me out please
sounds to me like a ring problem… Do a compression test and see…
or head gasket if u dont have compression itll misfire how does it perform under boost?
lol are the sprkplugs good
i had my car started again today …i let the motor run and i started to unclip the injectors. i uncliped the first one and the car almost died uncliped the second it did the same thing. then i uncliped the thrid one and the car was running the same… i have rc 550s is there any way i can save them or they just junk??
check plugs first
make sure there not fouled up or that there not melted or something
make sure ur gettting spark to cly 3
if ur not it will misfire…
make sure compression is good
if u have no compression in cly 3 then it will misfire but may come good underboost because the boost will give it compression
check injector…
