Hello. I have a friend that has a 2000 Gsr integra.
His friend help him put a test pipe in a while ago, he said they had to stretch the engine harness a bit to get the o2 sensor pluged in. After the install, the speedo did not work, no vtec, and the car was not charging.
They removed the test pipe and reinstalled the old stock pipe. He had a friend look at the wires near the o2 sensor, he could see where they have shorted out. He fixed those. He has put a new alternator, battery and vss on it. These did not do anything. He wants me to take a look at it now. Any ideas where i should start? Im assuming i have some wires shorting out somewhere. Also the #19 fuse ( whatever is vss/alternator...thats fine. Thanks
