i have a b18c in my ek and running on a si ecu. well i finished putting the manifold on and when i started it up the car's idle jumps around. its idles at 1000 and 2000rpm jumping back and forth. why does it do this? also anyone know how the t-fitting suppose to be connected. thanks.

 

that's happened a couple times to me when i did swaps for people. make sure you put the TPS and MAP sensor plugs back on correctly. both plugs are 3 prong, and will fit either sensor. also make sure you have a good seal between the TB and the manifold. later!

 

this crap happen to me on a b16 with an itr manifold..we searched for leaks forever and finally found out it was a leak in the gasket..go over all ur bolts and make sure theyre really tight...also check all ur vacums and check ur coolant and bleed it..
