I just swapped a 94 b18c1 into my 92 integra gs, and I wired the vtec solenoid, pressure switch and ground, knock sensor. Vtec works great and everything but every now and then I get a code 20 (electrical load sensor i think), and it wont let the car turn on. It only happens sometimes which is the weird part. I am currently running a p30 ecu, until I can find a obd1 p72. So what do I do about the code 20, where do I begin? Thanx
