Has a loss of power

I have a 94 Prelude VTEC with an H22a1 that has a loss of power. I just bought the car a week ago. When I first started driving the car the engine was running really good. There is no CEL on. I don't know what it is. I don't know if it is the timing. It is weird, because sometimes it will get the power back and then just lose it again. I can definitely tell it has a loss of power, its not running like an H22 should. Anyways, I replaced the spark plugs and changed the oil. I don't know if there is a bad connection. I took the negative terminal off the battery to change the fuel filter but I had to put the fuel filter back on because the bolt didn't fit the new one. I took the AEM air intake off and put it back on. I tightened the spark plugs to the right torque specs also. I don't know what is causing this. What should I check?

You may have sludge in the idle air bypass valve and or the throttle blade is sludged up, clean them with an approved spray cleaner, call honda and ask what they recommend. You may also have a loss of fuel press due to a defective check valve in the fuel pump, in that case cranking time is increased quite a bit, as much as 5 or 10 seconds.

Sounds like an ignition component failure check for proper resistance through primary and secondary ignition coil windings, refer to service repair manual for exact specs, also the ignitor magnetic pick up may be not up to snuff, the only other ignition component to replace or check is the ignition module and/or plug wires themselves, sometimes when extreme demand is put on the ignition system the plug wires must be high quality and completely isolated from one another. Spark plug wires when routing cannot come in contact with one another in the slightest proximity.

Unfortunately you probably need a new distributor. There are three pick-up coils mounted down inside the base of it. They go bad quite commonly. The unfortunate part is; the new distributor will come with a new cap, rotor, coil and module...which you have already bought. The distributors are not that expensive though, maybe you can sell the extra parts???

Sounds like the catalitic converter/s are clogged up. This would cause low air flow and low compression. I've seen them so bad that they dropped the compression down to 60 lbs.

read these words from the SM service manual first
"On 1990-95 Accord (except V-6) and 1992-95 Prelude, the codes are read from the check engine light after the two-wire service connector has been jumpered. On Accords, the service connector is under the dash on the passenger side. On Preludes, it is located behind the center console. Codes 1 through 9 are indicated by a series of short flashes; two-digit codes use a long flash for the first digit followed by the appropriate number of short flashes. For example, Code 14 would be indicated by 1 long flash followed by 4 short flashes. Codes are separated by a pause between displays. Multiple codes are transmitted in an alternating pattern. For example, a code 3 and 14 would be displayed as 3 short flashes (for Code 3) followed by the separator pause, then 1 long flash and 4 short flashes (for Code 14)."

Have a 94 honda prelude 2.4 Vtec won't accelarate past 2500 rpms in park or drive bows black smoke

Black smoke is an indication of a rich ( overfueled ) engine. Make sure the oil level is correct as a low level will affect the VTEC operating system and will cause a variation in valve timing. I would suspect the check engine light to be on if over fueled. You may need to have the operating system parameters scanned to determine if a sensor is acting up causing this issue.

Try replacing Oxygen sensor (top of exhaust pipe just rear of engine; 22mm ring-spanner job after cutting wires); though normally comes up with Code 1 on the MIL, this is the right bunch of symptoms.

93 honda prelude dohc vtec engine will not can be push started

Sounds like you accidently pulled the thin wire from you starter motor. Look at the connections at the end of the solenoid, mounted on starter motor.The thick red wire is Battery + next to that connection is a smaller male push- on terminal, locate loose wire (thin) in the same area and reconnect to male push-on terminal on solenoid or check if earth cable between body/battery to engine wasnt removed in the process.Also some vehicles you have to engage the clutch before starting, check for a switch located on clutch pedal where master cylinder connects to clutch pedal (Is clutch switch mounted and wiring connected?)
