HI Thanks for the info. For now i've changed the ignition spark amplifier, this part ...it resides on the airbox. The previous owner did a half assed job with it and it was not attached to the cooling fins (one bolt was broken off). If the symptoms appear again the next on the list is the MAF as you all suggested. For now the car runs perfectly, quite a lot better after i replaced the part mentioned above....

Can, please an admin change the title to Octavia Mk1 1.8t-->Stalling issues? I tried immediately after posting but i can't see any Edit button...

Hi guys! I have an interesting issue with my 1999 1.8t AGU octavia (cable operated throttle). Sometimes (let's say once every 14 days..) my car after accelerating in a higher gear(4th and 5th mostly) from lower speeds start stuttering, losses almost all power and if you release the throttle it stalls completely. If i restart the car, everything runs fine!. So i guess it's an electronic issue but a sensor which doesn't log error when temporarily faulty?? I checked for fault codes...nothing. I changed fuel filter and crankshaft sensor, still no change. I have two suspects: 1. MAF 2. CamShaft sensor 3. Vacuum leak? 5. PCV? interestingly if i unplug the MAF while the car is idling, nothing changes, car runs fine but when i plug it back it stalls. If i add a little throttle while plugging back the MAF, it will keep idling normally. I disconnected the TPS sensor and the car doesn't stall, just a little higher idle. So i guess the TPS can't cause stalling?? Any help appreciated! Thanks!
