d16z6 rough start up/idle/ cel 43 help!
Hi HT,
I am having a problem with my d16z6, running on p29 pistons, stock ecu, bolt-ons, stock fuel system etc.
When i start the car the idle jumps up and down and bogs a lot! almost about to shut off. It will finally stabilize and a min or so later the cel 43(fuel supply system) comes on.
I've changed my o2 sensor, map sensor, tested fuel pump, got new injectors( running stock ones again ). i just can't figure it out.
Weird thing is, after its warmed up for a while... I can shut off the car and restart the car and the CEL doesn't come on( sometimes ). All day today, it wasn't on. Only during warm up but after full warm it stays off once i turn off and on the car...
any obvious fixes or tests I can do to help me solve my problem?
any thought?
thanks!

I put a bosch o2 sensor in it brand new, Think maybe the header is leaking where the runners meet the b-pipe... no brand headers that came with the car. I'll try swapping my stock header on and see if that helps.
