Blowing 20amp Fuse after header install

[cop-ss]

I have a 2000 Camaro SS. I just had headers installed. Cats went away and rear O2 sensor code disabled. Front O2 sensors were spliced/lengthened. Problem is, the 20amp fuse for ENG SEN keeps blowing. This fuse protects MAF, heated O2 sensor, skip shift solenoid, reverse lockout solenoid and the brake switch. I also get a low (2.32) reading with my MAF when the fuse blows, but the engine seems to run fine. Any ideas?

I would definately suggest looking for a short, headers might have burned through a wire insulation, or maybe something to do with the splicing of the O2 sensor wires.

Yep, look at the 02 wiring - friend of mine had the same issue.

Mine did the same thing on the passenger side header, it would short and pop the fuse.

Thanks for the good advice from all of you! That's kinda what I thought it might be, but it always helps to have the opinion of folks that know what their talking about...
