hi Brothers i just bought a corsa utility 1.7 DTI and its due for service, so i wanted to ask if its normal to have a slow take off and struggle to pick up in a steep hill?
If it's a diesel, the first thing I would do is replace the fuel filters to get more power. Do the air cleaner too. It has no spark plugs to service. If it has over 100K miles, have the timing belt inspected/replaced. If the power loss occurred suddenly, the timing belt may have jumped a cog or two putting the valves out of timing, causing that power loss. Don't wait for it to break and cause engine damage.
