low idling and little shaking
 

just got this 87 supra and we rebuilt a 7mge engine for it with the works and we just put it in and the car is idling low and it has a lil shake to it there is no clunking or noice going on but we where thinking the timing was off on the car but we double checked that and it's not the we had to replace the tps (throtle postion sensor) and that helped but it still seems off. we are thinking it is the distrubtor but not sure yet any help guys this is my 2nd supra and so this one just seems off when its idling
