Engine Performance problem
1993 Honda Prelude 4 cyl Front Wheel Drive Manual 88000 miles
My car idles fine but accelerates slow until it hits about three thousand rpm, the car is also leaking oil on the right hand side. What could cause these problems? I only have one O2 sensor on the car and ive been told that it could be that ive already replaced the cam seal and valve cover gaskets. As well as the intake gaskets.
Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)
Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include: Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires

Thank you for your help, a few of those things I have already checked into but I will check itto the rest of them and let you know how it goes. Im replacing the O2 sensor today, that what alot of mechanics said it was going to be.
