Engine stumble on acceleration
 

We recently build a new fuel injection wiring harness for my '74 2.0 and I am trying to run down some issues. I have also been chasing some electrical gremlins and they might be related but I don't know. After all was back together, took it out for a test run and it was accelerating well but constant throttle was horrible. The TPS was adjusted but even unplugging it, the missing/bucking was still there. After some "wire-wiggling-investigation", one harness wire (ground) going into the fuse block was loose and the T-2 sensor was bad. Replaced the sensor and fired it up with good steady idle and no missing/bucking at constant speed but now it stumbles when accelerating. Unplugged the TPS and still stumbles. Testing the TPS, I get 19 "clicks". Is this an electrical problem somewhere else in the car? I replaced all the fuses with new (per Dave on another thread, seems to have fixed the gauges). I am not sure what to check, now. Any suggestions? Thanks.
