Question about 1992 Honda Prelude
Smaller/cheaper things first of course..after it began to "buck" wild like lol.... vaccum leaks, fuel issues, and elec. connectors all good.I was getting 5 codes from the OBD plug under the dash..I changed the fuel and air filters. no change. I replaced the oxygen sensor...ren better/cleaner but no real change. I changed the plugs and wires and still it continured to "buck". It almost seemed to loose all power then kick back on but all lights and cig. lighter...stuff like that worked fine.I blocked the Japanees annoyance valve and the lopeing seemed to stop. I changed the coil and finally the distributor and 4/5 codes were gone after changing the distr...now only a code 23 remains (crankshaft angle positioning sensor), I looked it up, couldnt find it in the book I have so I called auto store and was told that there is none on my vehicle...comes up as a camshaft syncronizer. It ran great on the test drive until suddenly it quietly lost all engine power, shut down and i was towed home, couldn't find the issue. Does anyone have an idea of what i can do now???
My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.

Take off the distributor cap. Check the star wheel that is splined to the distributor shaft that the pick-up coil uses. Make sure this wheel is not loose on the distributor shaft. It is right above the pick-up. If it is loose, replace the distributor. This is a common problem. If it needs one, all the part stores stock the distributor.

SOURCE: Hesitation and stumbling.
Before you do that, check which thermostat it has in it, if it has one that is letting it get too warm or not completely up to temp when the computer think it should be, it would cause this. My 2000 crown vic did the same thing and thats what it was.

Find an inductive pickup indicator for spark. Place on distributor cap to see if spark is at coil internal tower. If no spark at internal tower, look at ignition module or pickup coil. Ignition modules are prone to failure on 626's. But if you have spark at tower but not at the wire end, then your rotor is gone.

It sounds like fuel starved at higher speeds. i would change the fuel filter first if this does'nt help check the fuel pressure
