2.0 si problem

[outrun]

Got an 1986 Honda Prelude Si 2.0 Fuel Injected engine. In hard to moderate acceleration the car backfires through what sounds like the airbox or intake. Got any ideas? All would be appreciated!

Check your spark plugs first of all, they could be misfiring. If you pull it out and the center electrode is rounded off, you are way past due in changing your plugs. Do you have starting problems as well?

This is my brother's car & he says that he has not experienced any starting problems. The car has brand new plugs, wires, etc. The backfiring or "popping" sound makes me think that it could be an airflow meter. This could show up as code in the computer, but I haven't checked that yet. I might add that when running well, this can runs with & preforms as well as many newer Prelude(s) that I have driven.

well it doesnt have an airflow meter, but it does have a MAP sensor (Manifold Absolute Pressure)

yourn cam timing is probably off. does it seem to smooth out as you increase revs?
