    Exclamation Audi b7 A4 possible engine problem?

    Hi guys,

    I"m a newbie here, I've been using these forums to help with the previous issue on my car and they have helped a lot. Unfortunately, a new issue has come up and I'm just about out of ideas on what it could be causing this. Little run down, my current daily driver is an a4 b7 Quattro s-line manual, it has the 2.0 engine in it. Randomly throughout the past couple of weeks, I'll be driving normally(not aggressive) and out of nowhere it feels like I slammed on my breaks for a split second. The rpm needle will usually dip down anywhere for 1k-2k, and then go back to normal. This has happened while accelerating and cruising on the highway. A few times this has happened when leaving a red light and unfortunately the car stalls out. I've cleaned out the TB and MAF sensor and the cam follower, timing belt, head gasket, water pump and spark plugs have all been replaced, within the last 15k. No codes have been thrown yet. This is my daily driver and I'm afraid that something else might break due to how violent this can be sometimes when it occurs, any help would be much appreciated.
