Ok so I have a Jdm B20B in my 96 Lx sedan. Im running a Ls obd2 ecu. First of all my car has been acting weird at random..... It will run fine then it will start to hesitate/missfire faintly then it will get worse. Eventually it will just shut of like i have no electric... some times it will come back to life.... most times it just dies... I can start it right after this happens and it runs fine for a min then it starts all over again. Its not my alternator... and I changed my plugs..fuel pump.. and fuel filter in hopes that it wasnt getting fuel. it helped for a week but now its doing it again. i have cel code 17 Speed sensor... 20 Electrical Load Dector??.. 41 Primary o2 sensor.. and 65 secoundary o2 sensor... im stumped. any help is greatly appreciated. Thanks.

 

first thing u should do is get the cel's taken care of and then go from there. check your pins inside the vss and see if any of the prongs are broken i had the problem before, code 20 im not sure what that is but search it and you will find out, make sure your o2's are connected if so possibly there bad

 

If the readings from the o2 sensors are bad enough it will cause the car to do exactly what you are describing. Like he said ^ take care of the CELs.
