I've completed my 1.8 to 2.0 motor swap and have my car running really good, except the TPS is worn right around the partially open throttle position.
I've cleaned the surface and the contacts with 2000 grit sandpaper and then used Deoxit electrial contact cleaner. This helped as it only hesitates/bucks at the barely open throttle position and cleared up the issue at positions further along the path of travel. I imagine that it's worn right at the spot where you're most often running at. I searched but couldn't find any threads on repairing this. What I want to do is move the circuit board to the right or left, so that the contacts run on a fresh part of the board. Any ideas on how to separate the circuit board from the metal body and how best to reattach it? It looks like it may be soldered at the bottom right corner. |

dave a ,local shop told me AA has the boards too ? can you confirm ? yours ? or their own ? Probably mine. Last week, George expressed interest in purchasing them. When we spoke, he didn't indicate that he had another source. Glad to hear he's preselling them. Now I just need to get a validation platform... |
