hello everyone, im new on this sight but was wondering if anyone may have suggestions for my problem. i have a 93 civic cx with a mini me swap. im using a d15b7 block and internals, a d16z6 top end and a chipped p28 ecu. at idle the car runs fine, as soon as i give it gas it dies. i have checked the fuel pump, injectors and lines but still cant figure it out. any help or suggestions would be greatly appreciated. thanks

check your fuel pressure regulator. make sure its fully functional and that the vac line is intact. but you decription sounds more like a map sensor issue. if you have a firewall mounted senor check your vac lines. there should be one line off the tb that with a tee fitting that runs one line to the bottom of the sensor and one to the side of the sensor next to the harness connector. if this is correct then try swaping the sensor. for tb mounted sensors just make sure its well sealed. remove and inspect the o-ring under it. replace if damaged. if not replace the sensor. this may fix your issue. also make sure that your wires are correct. follow a scematic to make sure you have the right connector hooked to the right sensor. if mixed up the motor wont operate correctly. also make sure that the wires you ran for the 4 wire o2 and the vtec solenoid are in there correct location at the ecu. occasionaly you have to de-pin and re-pin a few wires at the ecu. you did run the wires from the engine harness to the ecu right? check your codes if you have a CEL.

could be a number of things those nick. like when jays fuel filter was clogged and the car kept dying on us on the way to the junk yard. it could be as simple as something like that.

OP make sure you check the fuel filter too. a clogged fuel filter will cause this issue as well.
