Hello,

My prelude is having an issue that i am having a LOT of trouble identifying. It seems to idle decently however when i put it in gear, and try to accelerate, i am barely accelerating at times, and when its at its worse, i'll have my foot to the floor and barely will be gaining speed. It's to the point that it is not driveable due to that issue. I'll list below my vehicle specs and the parts that i've changed, as well as parts incoming. If anyone has an idea on what i should check or replace, please let me know. I'm at the point to where i'll buy a part and just put it on, if it's likely to be the suspect.

Check Engine Light Issue:

The check engine light will come on at times when i'm trying to accelerate and its at its worse, however it leaves NO code. I have verified that the computer does leave codes. I disconnected the Temp sensor and the CEL came on, i then tested to see if it left a code with the jumper wire method, and it specifically showed the code that matched the temp sensor i had disconnected. (sad face)

Vehicle:

1993 Honda Prelude
2.3 SI

Parts Replaced:

Spark Plugs
Oxygen Sensor
MAP Sensor
Fuel Pump
Fuel Injectors
Fuel filter (2-3 months ago)

Parts incoming:

Throttle Position Sensor
Ignition Module
Catalytic Converter

you could clean fitv, egr and iacv in the name of basic maintenance

Spark plug, Spark wires, Coil pack, TPS, IAT, IACV. Change those, can clean IACV. Also I would check for air leaks.... And hopefully that should do it.

Replace the fuel filter again. I had the same problem and solved it by replacing the fuel filter. Its worth a shot. Not very expensive. Maybe you have contaminated fuel?

spark plug wires.
possible break, or may have seperated slightly when you pulled the wires off the plugs. Would allow enough spark to bridge gap and detonate during idle, but not enough juice while driving.
Check to be sure the wires are all tight down on the plugs, if no change, then replace wires.
