after swap, xj doesnt accelerate??

just swapped in a ZJ 4.0 in my 00 XJ, starts fine, stumbles 3 times after start, reverse works perfectly, but it barely moves forward/accelerate? throttle seems normal. oh and the exhuast isnt hooked up, just shooting out the headers for now

Was the "no bus" there before the swap?

no before it worked perfectly, i just realized it isnt the tranny, reverse and forward do the same thing, the throttle doesnt work well, if i give it any gas, it stumbles
