I have a Bosch 3.2 N/A MAF sensor inside the V8 MAF housing and a V8 N/A Throttle body. Now that I'm rechecking sources (needswings & the files on the fb group) I don't see anything mentioning the V8 Throttlebody. But the parts interchange for the TB according to rockauto says they are the same.

I will still order a new Throttle body gasket and swap back to the V6 throttle and MAF housing and see if this remedies it.
