I recently installed a set of BBK shorty headers on my 04 GT. I used the gaskets that came with the set and they turned out to be crap and leaked very badly. I replaced the passenger side gaskets with Ford MLS gaskets but the drivers side is still leaking pretty bad and I have to work so it will be a few days before I replace that side.
Before I installed the headers the car ran perfectly but now when I am idling it idles normally then drops down to about 500rpm for a few seconds and the goes back to normal and keeps going back and forth.
Would the exhaust leak cause this?
