Bought this car already swapped over with an s14sr in a s13 chasis. Everything apperas pretty much stock except the usual mods, exhuast, fmic. Anyways i was driving it for a while and it ran really strong and pulled pretty hard. i wanna say that when i first got it i think it had this problem but it was so minor of a hesitation that i looked right past it. recently i pulled out the stock turbo and put in a gt2871r, the car is not tuned so i dont expect it to run great. The car always starts and holds an idle but when start driving it completely cuts out randomly. ill be cruising on the highway at a steady speed with my foot on the pedal then out of no where the car will just loose all power as if someone turned the car off once the rpms drop after a second or 2 power kicks back in. I hooked upa wideband to check the afrs with the new turbo and seems like everytime the car dies its leaning waaaaaaaaaaay out and once power comes in despite being on the lean side the numbers are ok. Im thinking its the fuel pump just cause the fact that it leaning out and happens noticeably more when the car is low on fuel. What do you think?
