Hi,
I needed a new engine for my 98 accord. It had an F23A1 in it. I got an import motor that was an F23A.
My mechanic noticed that the F23A had an ERG emissions sensor on it or something so removed it. He took the timing belt kit off my old engine and put it on my new engine. Some sensors were damaged on the new engine so he replaced them with my old sensors. They changed exhaust outlet and upper part of intake manifold on the new engine with my old engine. They also changed the wiring loom and rocker cover on the new engine with the ones from the old engine.
Now it starts, but it doesn't run properly. It cannot be driven. It runs really rough and if u accelerate hard it chokes and dies. You can accelerate slowly and get the revs up but it runs very rough and can stall. Fuel pressure is fine.
Any ideas? What could be causing this problem? What are the differences between these engines? Could the missing emissions sensor be the problem?
Thanks,
Adam
