Hello, my car is occasionally being a pos.
It is a 2001 gtp with only 91k on it and it randomly it the tach will go to zero and the tcs off light will come on.
Around 50mph (and always around 50mph) the car will kind of shudder. I thought it was the transmission but i guess it could be the torque converter?
Also the car will randomly stall at any speed. This happens about every other time i go to work. A lot of fun let me tell you.
I have tried a dhp pcm and the stock pcm and it does all of these things on both computers.
Im thinking about fixing this somehow then selling it for a car that doesn't have finicky electrical problems.
Thanks
