Thanks Mudski, I got a new MAF off you a few weeks back but is doing the same thing before replacing somI would be thinking it is something else. Air filter is fairly new, about 3 or 4 months and still pretty clean. Bit dark now but I will check for split pipes tomorrow. Not sure about the intercooler. It has got some crap on it but not any specific section. A new one coming next pay maybe if I can work it in to budget. I will keep looking but may need to get it to someone with some skills. Lol. Not me. Thanks heaps
