1996 Honda Accord 4 cyl Front Wheel Drive Manual 112k miles
I had a bad cylinder in my old engine and it was obviously running extremely rough so I purchased a used engine with 112k miles on it from a certified wrecker. Had a local shop install the engine, swapping all components except for coil and injectors.
After R&R new engine starts and idles rough but has even less power than my previous engine did on 3 cylinders. All cylinders in new engine have over 160 lbs and has spark and fuel. Timing is checked. Computer says the O2 sensors are out on both manifold and catalytic conv. And that it is running too lean.
When driving it feels like the engine is fighting itself for power. Revs, but has no increase in torque or acceleration.
Had catalytic converter checked and even went as far as to drop the entire exhaust to see if that was restricting it but no change in power.
Could this be a fuel pump issue? Throttle positioning sensor?
Where should we start? I'm at a loss.
