Blew tops of pistons

Those afr numbers seem about right to me.

Gotta mess with the fuel trim though it's adding a lot of fuel. I would check for a vacuum leak.
 




Ok ill try clamping all my hoses. I can't believe the intake manifold would have a leak or throttle body I mean its been put together by my old tech teacher that built his own drag car.
 


Yes and I think yes. Don't remember if your year has the access panel in the trunk.

With a leak at the manifold the o2 readings are incorrect so the computer won't add the proper amount of fuel. May run rich usually or even lean but either way it's wrong.
 
So i sprayed some carb cleaner around on my hoses and didnt really notice any idle changes, kinda hard with just straight headers. But i got some more numbers. My MAF reads from .69-.70 my MAP reads 32-33 and my O2 reads 180-900 constantly changing. I still need to get clamps for my headers but the part store didnt have any.
 
Look at fuel trims while you spray. Thought I mentioned it before Sorry. If the leak is large You'll hear the idle change but small leaks are much more subtle. Watch your fuel trim before spraying...then while you spray it should start to go negative as its pulling fuel.

After all of this your engine is going to be so freaking clean LOL.
