A new problem arises

[HercGTI]

today the golf is doing something else weird..... if the revs drop below 2000rpm while driving, it really struggles to get up again.... bogs down really low to the light of almost cutting out..... any ideas? I'm thinking the IAC?

now it's coughing and spluttering at low revs......

Is it Digifant?

Could be a loose vacum line?

Also check all ignition and coil leads aren't loose.

Yep, it's a digi..... started after I changed the thermo fan..... might've loosened some leads while pulling the old fan out.

ended up being a loose lead.... seems good now
