car has been running pretty good for the last 3 weeks or so. still working out the little problems and it seems as im getting close but this one is really bothering me, esp since it dosen;t happen every day. now im getting a little scared to drive it anywhere though.
basically when crusing or comming to a stop the car is dieing every few times. to be more specific ill be cruising on the highway doing 75mph or so. 1/8th-1/4 throttle steady, blah car cuts out completely, ususally have to pump the gas 1 or 2 times and it fires right back up and goes fine. sometimes comming to stop and stop signs the car dies or wants to and it either shows full lean or 10.0 on the wideband. so anyway i plugged in nistune as soon as this happened and i always get 3 codes. 1 fuel temp sensor (normal since its z32 ecu on rb25) AFM code, and speed sensor. not sure where the speed sensor is comming from but yes it looks like im getting a code for my maf. so i checked the wiring, i actually moved the 12v ground which was on the wire harness tied into that terminal that gets grounded to the intake and i moved it to its own chasis ground seperate from eveyrthing. that didn't help one bit. now im just pretty much stuck. i can't see if being a bad maf becuase somedays after driving the car 100 miles it dosen;t do it and runs fine, then other days im scared to drive it 5. im really stumped here but i need some suggestions. i tried datalonging in nistune one day to see if i could find anything but of course that day the car decided to run perfect. but help me out guys im on a mission to get this solved so i can make it to a new england 240 meet this weekend and hopefully start hitting some drift evetns soon but i don;t quite trust the car yet.
