I just picked up a 94 samurai a little over a week ago. drove her all the way from iowa to michigan. no big problems on the way home, just a broken speedometer cable. anyway, to the issue at hand. it seems like i have lost a lot of horsepower in the past week. at low rpms, the engine will sound like it's being bogged down until i hit about 3000, then i'll get pulled back into my seat. i don't have enough power to hold 70 mph on a flat road in 5th gear. sometimes, i can't even get moving if i'm on a hill, the engine will spit and sputter like i'm trying to take off in 3rd gear (yes, i did make sure i wasn't in 3rd). i looked around to find one with fuel injection to hopefully avoid issues like this, but it seems that didn't work. plugs are brand new bosh platinum +2s; wires, distributor cap, and coil are all brand new stock replacement. not sure about the distributor rotor. the check engine idiot light is on, but the only code it'll give me is because of the speedometer cable. I know the 1.3L isn't a huge powerhouse, but i'd like to get her to perform as a good daily driver that can handle going down the interstate without holding up traffic. what else should i be looking at to get some of the lost hp?
