Hi guys,
I just recently had a new manifold fab'd for my miata so I could run an external wastegate. Now that the cars back, im having a problem. When I get into boost, I will hear a sound like a freaking shotgun, and the car will lose all power. I checked the plugs, and they are bright white after only about an hour of it running. Sounds like a fuel issue? The only thing I could think of is that I ran the vacuum for the fpr t'd off the bov line, which draws vacuum from the mani. Also, I wish I could have a cel, but im running haltech. Any suggestions?

 

white plugs= super lean. u need to get a wideband on that thing and see what your AFRs are. looks like u have a serious fuel problem or need a re-tune

 

Definately...It seems to run fine part throttle, its just under boost. The problem im having is that it was fine before I took it in, so im not sure what could have made it run so lean.

 

Some jackass at the dealership probably hotrodded your car around town like on "ferris buelers day off"

 

lol, nah, I had the battery out and the throttle cable disconnected...it was also at a very reputable shop called autolab, which some may know.

 

maybe something is not hooked up properly.
