Hi everyone! My rig is a rail frame dune buggy with an old legacy an ej22 motor. I built it last year and now I am in the Glamis sand dunes for a week on vacation. I've been having a reoccurring problem with my throttle cutting out under power. It seems to be happening when its hot and idling for a while. The idle will start to stumble and fluctuate. Then when I start to give it gas it hesitates and is like "on-off" when my pedal is down. Sometimes I can get it back to normal under heavy acceleration but other times it is so bad that the engine dies. The problem is only getting worse. Now it happens every time I ride and is really putting a kink in my vacation. I've lurked every thread and forum but have found nothing that matched what I had. If anything, I'm leaning toward a MAF problem. I don't think it could be an IACV problem as it happens with a lot of throttle. I have already replaced the throttle position sensor. I popped the cover off the MAF and re-soldered the 4 contacts to the plug. I don't have access to a new MAF where I am at so it was the best thing I could do. Still nothing. Any help is much appreciated! Thank you in advance!
