Hey guys I recently did a fresh engine build after spinning a bearing on my 01 s2000. The car never ran quite right since I bought it. It used to misfire and it ran a code for the ecu being faulty. After the rebuild I replaced the battery, alternator, Plugs and packs, ecu, and the engine and dash harness. The car now runs pretty well but after about 15 or so miles of driving the car will shutter and die when I put in the clutch. The lights dim and the car won’t start back up unless I jump it. I have double checked my grounds and they are good and I have rechecked the battery and alternator and both are testing ok. I changed a few fuses but it’s still doing the same thing. It is throwing a few check codes p1298 for the electric load detector. (I borrowed a friends from his crashed s2000 and I’m still having the issue) and p0135, p0141 for the o2 sensors. Thanks for all your help in advance.

thanks for the quick response I’ll change the sub forum thanks
