Hey, here's a stupid question. Anyone know where I can get a "GOOD" 1973 2.0 throttle positioner. I've developed that cursed bucking just off idle during slow acceleration but the rest of the power band is fine. I've cleaned up the circuit board as best I can and a new board may fix my problem but I'm not sure the contacts are all that great either so I'd just as soon replace the whole relay. Yeah, yeah, I know. put a carb on it. Just trying to stay as original as possible.

I've got repair kits for the 2.0liter cars and the late 1.7liter cars. The new boards can help if the problem is caused by worn traces on the board.
However, there are other potential source of trouble -- the wipers can get corroded, there are little directional leaf contacts in the stem of the sensor that can corrode, and let's not forget about aged wiring terminals or broken wires. So, yeah, a new board can help, but everything else needs to be OK. A replacement board is only $35. If you need one, send me a PM. |
