Hi guys,

I have reduced my problem down to the thermistor in the air flow meter. It is really damaged and since in Venezuela there are no used parts to choose from, I was thinking to replace just the thermistor. My thermistor is so weathered down that there are no visible numbers or letters written on it. So my question is if anybody knows the specs for the thermistor.
Having those would allow me to buy one at an electronics supply and replace it. The of the air flow meter is good enough condition to work. I can start the engine by blowing some hot air with a hair dryer. Once the engine is warm, it will start at once every time.
Any help with this is highly appreciated.

300 Ohms at 20°C should be the value you look for. I'm not sure if the response should be linear or logarithmic but it should be Negative Temperature Coefficient (NTC) though.

How do you suppose it got "weathered down?" Was the engine run without an air filter; was the engine habitually backfiring?

Could you post a photo of it?
