Hi i have a Golf Cabriolet 1999 1.6 it has an erratic idle, i have checked air filter and sprayed carb cleaner into the inlet.
im going to change the fuel filter next.
Any suggestions as to what should be done/checked next?
What happened when you sprayed carb cleaner into the inlet? You could use carb cleaner/propane to leak chase the vacuum hoses.
Is the EGR valve functioning properly?
If the engine has an idle control motor, is that functioning?
