That sounds like the AC Compressor clutch engagement sudden load. In that the Engine Management should lift engine revs to counter the sudden load on the engine from the Compressor via A/C clutch engagement. Without looking at diagnostics which is engine specific I'd say either A/C off/on switching or sensing is not working right.rockhopper353 wrote: ↑Mon Dec 11, 2017 8:43 pm OK so driving home from work tonight I've turned the air conditioning off and it doesn't do it, the revs just drop to 750rpm which i think is normal, this is also the case with the AC off but the blower still on.
Turn the AC on and dip the clutch and the revs drop to 500rpm and the car stutters before rising back up to 750rpm, any thoughts please.
