hey guys! my brother and i are looking to buy a 93 honda civic hatch si this sunday but the guy says there's a problem with the engine. i just wanted to asked for advice and see how bad the problem is before buying it and having to deal with a really messed up car.
he said when you push the car harder then normal driving, it would back fire or something at 4000rpm and won't go any further. but if you were to drive it normally then there isn't any problems.... what might be causing this?!
if i can get some info asap before i buy the car this sunday, it'd be great! thanks people!
