well bad news....i replaced the coolant sensor and cleared the computer memory by disconnecting the battery for ten minutes. I just drove it home about 15 miles coming from a friends house. It seemed to accelerate better but i think that is because i reset the memory because when i got to the driveway and hooked up my laptop again to read the live data it still shows 47-48 degrees celcius! when i tested the resistance across the pins on the sensor it said 198 ohms which should translate to 190 degrees farhenheit or about 90 degrees celcius! Could the translating software be wrong on tuner pro or is there some weird wiring problem on my truck? Or is the ECM not translating the voltage properly? Plus the engine still sounds funny on acceleration like the wrong fuel ratio or timing not being advanced properly. Damn.
