Title: popping sound from exhaust
Post by: performancevw on 12 July 2013, 19:59

hello

I have a mk3 golf 1.4, its having a popping sound coming from exhaust more like pop pop pop every micro second. And when sitting inside the car I can feel that car vibration as if its misfiring which it is. No idle issues though. just a misfire. I Had put on diagnostic but no fault codes at all. Tried new spark plugs, ht leads, coil, coolant temerature sensor etc so dont know what is causing this misfire/popping from exhaust. please advice what to look for, many thanks.

Yeah I have the same issue on my abf in my corrado with a long life exhaust, idles fine and performs great just the odd little missfire now and again, can barely feel it but it's there. Have changed leads, plugs, coil, lambda, oil, cleaned isv, New vac lines but still slightly there.

is the exhaust de-cat?
