Hi guys, Been trying to find answers with ongoing problems, initially had suspected MAF issue with little to no acceleration, replaced MAF and acceleration was back now having fault codes for air flow and ICV % which is down to an alarming 8% but spike up to 100% at times all over the place. I am preparing myself for a new injector pump if needed, but just interested in the wider patrol communities thoughts on this problem, any other cheaper fixes out there I can try first. I am unsure what the ICV % was before my issues as I've only just got my ECUTalk when my first fault code presented. Thanks in Advance any info greatly appreciated. Dan
