i bent mine pretty good from not hammering the firewall. its kinda hard to hammer the firewall headers in unless you have a air hammer.
i moved my o2 to the back of the cross over pipe. and it took a dump shortly afterwards. from being bent is my guess, as it was brand new when it got bent. but it also set a code telling me it was slow.
the idle surge? how much rpm is it jumping? like 500 rpm and sounds like its got the most bad ass cam ever installed? if so thats a huge vac leak. like the evap is off the tb big.
