Re: No power when climbing hills, losing speed & rpm's

Honda Civic EX 1999, 1.6 SOHC, 4 cylinder, 16 valve, V-TECH, Engine # D16Y8, 5 speed manual transmission

Replaced the timing belt, fuel filter. Whenever there's a call for power like when going up any grade of incline or when trying to get up to highway speed even with the accelerator floored the speed and rpm's continue to fall off. Sometimes need to shift down to 2nd gear in order to climb hills, however down shifting is not necessary when trying to reach highway speed, but still have to floor accelerator in order to get up to speed. What could be causing this problem? Thank you for your assistance in this matter.

Re: Re: No power when climbing hills, losing speed & rpm's

Assuming the timing belt was installed correctly (cam timing correct), and the ignition timing is also correct (if equipped with an adjustable distributor), I would first inspect the catalytic converter.

You can unbolt the exhaust at the bottom of the cat and look inside. If you see broken up debris instead of a uniform honeycomb grid, the cat is bad and obstructing the exhaust.

Next would be testing fuel pressure, and quality (contamination from water, diesel fuel, or high alcohol content (E85).

Check these 2 items first and please let us know how you make out.
