As above, where do you start looking for a vacuum leak and what would you use to diagnose a leak
Is there a checklist that I can go off to make sure I'm looking in the right places
I have the 1.4 cvh efi in a fiesta si 1995, car starts and runs and will run as long as it needs too but after startup it'll idle until the auto choke goes off then it just idles rough like it's hunting as though the air flow sensor is bad
So far I've changed plugs, leads, filters, MAF sensor 02 sensor, icv temp sensor on thermostat housing, thermostat itself, fuel filter and dear knows what else but I've exhausted all the replaceable parts that would cause a rough idle, I'm now at the air/vacuum leak stage but don't know where to start or how to go about it so hoping someone can help, thanks
