When driving up a hill my car suddenly moves very slowly, like at 15 -20 km/h and the rpm's only goes to like 2500 and then drops down quickly ( the needle in the gauge is bouncing at 2500 and back to like 1000 like every second but the car will not cut off.
The car is going a bit back and forward a lot when this happens. Car runs great on flat roads but once I start going up a hill this problem occurs. There is no loss of power or speed on flat roads.
I had a qg16 engine ( a 1.6) before in the car and the same problem occurred but the transmission felt like it was slipping and there was loss of power so I changed the engine to a qg18 ( a 1.8) and bought a new transmission.
After the engine change there is more power on flat roads and the transmission does not slip on hills. But there is the same problem of the car no being able to drive up a hill normal. If I make it at the top of a hill or halfway I have to pull over to stop for a while and when I continue to drive mostly on flat road again, the car drives normal.
There are no codes but the check engine light is on. All oils are at their levels and there are no leaks anywhere.
Please help me!
have the same problem?
