Question about Honda Odyssey
Car surges and when gets up to 70 MPH the RPM drops. No problems with starting or idling. Only acceleration.
I would start with a standard tune-up: new air filter, spark plugs (with proper gap), distributor cap and rotor button. Check the plug wires and replace them too if they look cracked or damaged at all.

Here is the most common cause of surges and stalls, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: S80 engine surge at idle
You could have a bad or contaminated Mass Air Flow (MAF) sensor. You can get a used one online for less then 100. You can also purchase a can of MAF sensor cleaner at a local auto supplies store and clean it. It located right at the air filter housing.

i gave my 944 turbo which had a idle problem. checked all the vacuum
attatchments, made sure all were connected. Checked coolant level.
Then cleaned the fuel pressure (part). ie the fuel rail attatchment, with carburettor cleaner then sprayed dry lube into it. Its running like a dream again. This part i am talking about has 3 inlets and is at the front of the fuel rail, when you take it out fuel runs out of it for a little while.
Hope this fixes the problem.
