So I've had my sr20det for awhile now and it just now started to run like crap.
It's pretty much stock except a z32 maf. It runs really good for like 5-10 min pulls hard then turns Into a slow turd. I already replaced the coolant temp sensor, and no boost Leaks, injector o rings are good, idk what else to try. Completely stock at with a ssqv an z32 maf. Fuel filter is z32 and Walboro 255

thats ur problem. cant use z32 maf on stock ecu, if it was ever running right with it seems unlikely, get a stock sr/sohc maf and switch it back!
