2003 Mitsubishi Outlander shaking problem

Year of vehicle: 2003
Make of vehicle (Ford/ Chevrolet): Mitsubishi
Model of vehicle ( Taurus/ Cavalier): Outlander
Engine size (2.0/ 5.7): 2.4
Mileage/Kilometers: 100K
when I drive on uphill at 40-50mph, the car will shake intermittently,It is like:
shaking---stop shaking for seconds---shaking----stop shaking for seconds---shaking.
pretty big...
I do not know whether it is related with the timing belt change, or not. I think I found this problem after I got the timing belt and water pump changed. But I am not very sure.
any comments for this? thank you!

Jan; You mentioned that this only happens 'uphill'. Under heavy fuel demand? Check engine or service engine soon light coming on? This could be a secondary misfire, or starving for fuel. Any backfiring associated with the 'shaking'?
If you get a check engine light, have the code(s) retrieved and post them. It is not uncommon to have a misfire that doesn't last long enough for the computer to pick it up, but if it did, that would simplify things. If you haven't had the fuel filter replaced in the past year, you may want to do that as a maintenance thing.

Hi Loren,
Thank you very much for reply~
Yes, it only happens 'uphill' under heavy fuel demand. And when it was shaking, if i release the gas pedal, the shaking is gone.
No light (Check engine or service engine soon light coming ) is on.
(what symptoms if backfiring happens? It is like huge noise? )the engine is fine, no noise.
I will check the fuel filter, if necessary I will change it. Thank you point it out.
Thank you very much!

Jan; No, I wouldn't advise replacing the pump/filter assy. without proper diagnostics, first. A fuel pressure/volume test should be done to see if that is even the problem. Most shops will have the equipment to do this.
