I’ve got a weird Intermittent problem, when I’m coming to a stop in traffic and have my foot on the break the engine shudders and the revs dip, it feels like it’s almost going to stall (it never actually does stall) and then recovers and continues to idle normally. It’s been happening since I bought the car car is 15 years old I got it last year. The car has had a new MAF and IACV and it still has the same issue. I can’t replicate the issue when stationary it only happens when I’ve just come to a stop. Its a manual and the clutch pedal Is pressed in when stopping. Any clues?
