Irratic idle/poor running. Gas readings; CO 0.00 CO2 8.36 HC 7 O2 9.4 Cannot find an air leak anywhere. Lamda sensor stays at 20mv, when disconnected defaults to 450mv but gas readings don,t change. Fuel pressure @ 50psi, injector duration around 5ms @ idle. Fault codes cleared, roadtested & reread P0170 fuel correction malfunction, cyl misfire1,2,3,4. I,m sure we,re missing something simple  David |
