Inlet Manifold Question

[Impellor]

Hi Gents, just a quick question on whether a leaking inlet manifold will throw a fault code.

Cheers

Yep absolutely, missfire codes, lean/rich codes

Not always though

Like bionic said not always alan, if you suspect you have a vacuum/boost leak, easily checked at idle with car running by spraying some carbi clean or brake cleaner in a fine mist around all the gaskets/joiners and hoses. If there is a leak idle stability will be greatly compromised. You can also check using the scan tool by monitoring IAC KAM3 and IAC TRIM, you add them together but I cant remember what the value indicating a vac leak was! That ol saying use it or lose it, and ive been away from ford too long to remember. I might have a search on here to see id I did post it up years ago or check the tsb's I have at home. There was a bulletin on it....getting old doesnt help either, 26 yo now so its all down hill now :(

Yep vac leak can usually be logged with kam 3 and trim. Try spraying some ether or carby cleaner though first
