Code 34 with weird symptoms

I have an '88 L98 with mods below....

I just recently put on a set of AS&M semi-siamesed runners. When I first started the car I immediately got a code 34. The car has an irregular idle, and when I tap the accelerated the engine goes berserk like it's WOT.

When I unplug the MAF I can't get the car to start at all.

When I unplug the TPS I have the same symptoms.

Any suggestions?

Matt,

You have to be very careful about the selection and orientation of the lower runner gaskets around the EGR and Cold Start distribution passages. They are similar and can be incorrectly installed or shift on installation.
