I checked the OHMS of the number 2 temp sensor as specified by the maintenance manual. Bentley Manual. It was reading around 7,000 OHMS when it should of been around 2,500 OHMS. So I ordered a new sensor from Aircooled.net I installed it last night and as I suspected the car ran rough so I had to re-adjust the air/fuel ratio by the adjustment screw under the air box. I adjusted it to full rich I believe and it still was not enough. The box had been opened before so I suspect the whole air flow meter needs to be opened again and re- adjusted. I just don't know how exactly.
My other question is this. When I took the old sensor off. It had this adapter on the end of it that goes between the sensor and the engine head. It plugs in right between just like an electrical adapter but the ends of it are the same as the sensor and the port that it goes into. It looks like the end of a chisel without the wedge part as it's long but it just plugs in between the two. Do I need that part on there? I couldn't separate them so I put the new one on without it and it fits fine. The old part had a lot of rust on it which could of been the reason why there was more resistance than usual. What does this part do? Why is it there?
