ok cheack this out i have a 94 dx and it poped an ecu fuse one night and i found a burnt wire under the dash so i fixed it and thought i fixed my prob. but 3 days later it started all over again (what a damn headace) finaly i said skrew it and took it in and they said it was cause i extended my o2 sensor when i put on my header and he unpluged it and said drive like this and see how it does i ran it for like an hour and nothing yet but my friend extended his sensor the same way and his isnt grounding out so could this be the real reason?? just currious????

 

no i did that i had no problems just make sure u put loom over where u cut and make sure a good connection that means no but connetors

 

make a nice connection.. sodering iron and male female connectors with a nice tight crimp.

 

yeah i crimped them so i think that is the prob.
so i shouldnt have crimped them i should have soldered them?
