93 civic hesitation problem
i've posted about this before, but i'm going to give it another try.
my 93 civic has a hesitation when you accelerate right after start up/when engine is cold. Other than this, it runs okay once everything warms up. i've already checked the wires, changed the plugs, changed the fuel and air filter.

Re: 93 civic hesitation problem
O2 sensors come to mind...if they're on their way out, then the ECU might be leaning the fuel mixture out until the car warms up, because it's getting inaccurate info from the O2 sensors.
