Cylinder nro.3 running Lean/hot in ViPEC V Series Posted August 6, 2018 · Report reply 2 hours ago, Seitsonen_m said: Well, no good news. Bleeded The system For two hours. Engine cooling Works yes, but cant get pressure build up to cooling system.. hoses dont get hard.. Switched Fuel injector connectors between 3rd and 4th. Idled almost two hours when bleeding. Zero carbon build up on 3rd plug base Ring.. Cant get Idle drop under 1500rpm(im guessing this has to do something with almost zero pressure on cooling system) I know that when you take cooling hoses off from The throttle body. Idle Will Be high. Found out Bad radiator Cap. I wonder could this solve The whole problem running without cooling system pressure... Didn't have Time to test The Car now that i found that leak and got pressure Back to cooling system..
