- 2007 Buick Allure
Hi there! So I recently moved from somewhere super flat to somewhere with lots of hills and noticed that my car chugs when going uphill. It seems like the engine is not automatically getting the power/fuel it needs to adjust to going uphill, and I noticed the rpms stay where they were and don't automatically go higher to compensate. The engine light does not come on when this happens, and the chugging stops when I give it more gas. I thought it might be the throttle body, but I had that cleaned and it still happens. My car is a 2007 Buick Allure 3.8 with a little over 140,000 kms. Any ideas would be appreciated!
