A friend just gave me an '83 Accord LX hatchback to fix up. It drives fine on the highway, but I have several large hills around my house. I could be going 70 mph when I hit the bottom of those hills and I'll be down to about 30 or 35 when I get to the top. Most of these hills are less than 1/10th of a mile long. Any ideas what could be causing it to do that? I've changed out the plugs already. I'm just getting some ideas so I can start planning out what else I should check and change.

Thanks!

I would check your ignition timing. If it's way off, you'll be losing a lot of power. Also has anybody done a headgasket or timing belt? They may have put the timing belt on wrong, because a lot of the EK1 cam gears have two sets of timing marks, and it can be very confusing which ones to use to set the cam timing.

 

And make sure the catalytic converter is not plugged
