I used the car and have a scanmaster 3, in some cases,the data that display in scanmaster do not work fine, for example, no speed,but in the dashboard it's fine, no acceleration, the O2 trim almost always above 0.8, does not accelerate as it should, it feels slow, but a left it an hours and then everything's is fine.
Any idea what's wrong with my car?
is the ECU?
Thanks
