My race truck randomly started stalling and surging. When I give it some throttle it idles like it’s about stall, then surges then dies down if I get on throttle heavy. If I ease into it, I can get to about 2200rpms before it starts hesitating.
So I unhooked fpr and DESIRED maxes out with Actual to 29k then the truck stalls out. But I plug it back in and the truck will start right up
I’ve never seen desired max out before. I also unplugged fuel rail pressure sensor and that stalls the truck out too. Replaced the sensor, same thing.
Any ideas?! Fresh fuel, fresh filters. I’ve logged it and don’t see anything that catches my attention besides the desired rail pressure
this all started happening when I flashed in another tune I ran in the truck before Hand so I know the tunes fine
