The problem could be related to the tune up of the engine.. when the vehicle is traveling uphill there is more load on the engine, so if the engine spark plugs arent up to par they will missfire causing the hesitation your feeling .. damp conditions could also contribute the the misfire condition .. i recommend having the tune up parts checked and replaced as necessary.

If automatic, you may have transmission problems. Check the fluid level now! Method should be in your Owner's manual.

Transmission motnana missfire traveling


If your car is misfiring when driving then it could be your ignition module. I had the same problem and changed all plugs and wires multiple times, also had the coil pack fixed. It ended up being the ignition module. Try changing all plugs and wires then have the ignition module checked.

2006 Hyundai Elantra with 2.0 automatic with 111000 miles. Car is hesitating and begins shaking going up steep hills. Problem seems the worst at around 3000 rpm going up hill. The car wont stop shaking...


There's many reasons this can happen, but start simple. Fuel pump may be failing. Usually under load they can not supply the fuel the engine is demanding. (Up hill acceleration is a classic example). change the fuel filter first, if that doesn't not correct the problem, test fuel system pressure. (:
