Hi everyone. You've got new users from Finland
and sorry my bad english
I've read this forum for a while, but now i have problem that haven't solved by myself
My alfa 33 1.7ie has misfires under 2000rpm when engine is warm. When engine is cold or rpms more there isn't that problem. I have measured temperature sensors, fuel pressure and lambda. And checked that airleaks there can't be. I think the motor is running too lean, because cold engine runs well. Or problem could be in ignition, but how can i measure ignition parts and how the ignition timing should done. I read from autodata program that throttle position sensor's three wires should be bridged when timing is adjusted? Has anyone have that same proble or can anyone think where problem could be?
