Let us know what happens with new coils.

Well...  I put the new ignition coils in, and those fault codes went away, except Clutch Switch Malfunction, But it still ran rough after 5 seconds from startup, so went to get the new Clutch switch from Ford dealership today that was also a fault code, with a malfunction, so for curiosity we measured the new switch with multimeter with the old switch and it was exactly the same reading? So, don’t know if it really does fault after operating a bit or ECU/PCM is playing games?

 

While I was at Ford, I asked the Service Adviser that used to be a ford mechanic and worked on these BA’s back in the day about how it suddenly ran rough after 5 seconds from startup and I told him what the faults codes was and what I’ve replaced and he said its most probably a leaking inlet manifold gasket that he said was notorious back then on having this issue, as bolts might be loose and gasket leaking, so sounds like these inlet manifold bolts should have been checked/torqued at first service, as gasket settles?

 

When I got home, I looked at mine and you can see residue stains around this inlet gasket and I see you can spray brake cleaner around inlet manifold when running to see if rpm goes up with spray getting sucked in leak, if there is one and I see online you can do a smoke test as well into manifold for leak test.

 

And I have another new problem, as when I tested the new coils the first time, it started ok, but then a bit later tried again and it wouldn’t start or activate the starter motor, the lights on dash was all there and didn’t dim when trying to start, but on the Audio Display screen, there is the word- ‘’Code’’ and when I try to start, this screen Code word dims, But the dash lights don’t dim, But I cant put a code number in there, as the radio doesn’t work when pushed the on/off button to turn radio on, as I had the battery disconnected for few days while working on it, so don’t know if having battery disconnected for long period, that it does this, everything else works, head lights, dash light, locks/unlocks car, red panic alarm on keys all work ok, so what’s the go here? Sounds like a security function has activated so car won’t start. Thanks
