I used the program and I hooked up my turbo link to my car and at full throttle he's only showing 3.33 TPS reading which is low also the alternator is only showing 12.7 voltage. I am thinking that it may need to replace the alternator and TPS sensor. With the reading from TPS he's running lean..... When we turn the headlights off while the car is running, the voltage goes up to 13 but when we turn the headlights on it goes down to 12.7 or lower. that maybe a sign of a bad alternator or it is not charging since it maybe the original. What do you think about that and about the turbo link program given me the read out.
