can anyone figure out what was causing this?The car is stock, stripped, roll cage, stock b18a1 stock exhaust manifold with straight exhaust. it runs around 4.5k to 7k for 10-25 laps depending on the race, but i have had a fuel problem since i built this car which. happens after about 5-10 laps running in just second gear with out shifting then again every 2-3 after the first stall. im not hiting the rev limiter. the car cuts out and seems to pulsate fuel until it drops to 4k rpms. i have talked to others that race integras and they have had it too but nobody knows how to fix it. i noticed that if i shift gears when it stalls then i have full power again and can shift back down into second and run a few more laps before it does it again. I believe its something getting hot and sending a signal to the ecu to limit fuel, but what? or maybe i cut an important ground wire somewhere in the harness when i stripped out all the unneeded wiring?). i have replaced the engine harness, body harness, ecu, injectors, IAC, TB, distributor, about every sensor i can see, fuel pump, ignition switch. I can park my car and hold it at about 5500 rpms in neutral for about 2 minutes or so and it stalls like on the track until you completly let off the throttle. it has a fuel cell with factory pump and wired to a on off switch. also it does have steel fuel lines ran under the car (illegal to have fuel lines in drivers compartment). any help would be much appreciated. thank you
