94 honda accord 2.2l engine misfires at lower rpms
My accord acts like its missing around 2000 to 3000 rpms only while driving! I give it more fuel and it goes away and runs good but as soon as i back her down the engine starts to surge again. I changed plugs,cap,rotor,wires, and checked compression it was like around 150psi in each cylinder. Im at a loss here its driving me nuts. Could it be the internal coil or fuel injectors???? please help

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.
I would suggest you change out the fuel filter and then try it, if that doesn't change anything then pressure test the fuel pump to see if it is putting out the correct pressure, low fuel pressure causes this type of symptom
Engine light flashing along with the drop on RPMs is indicative of misfires. Connect a scan tool and see if any codes are stored this may give you a starting point. As for the clicking I'm not sure that it is related to the engine light but clicking when braking may be due to worn suspension/steering parts such as control arm bushings
Wrong spark plugs installed - causing too many misfires Timing problem - the ECC (Engine Control Computer) will give up after a short while if it cannot get the engine to operate in correct time clogged fuel filter clogged air filter clogged fuel strainer worn distributor cap/rotor failing fuel pump vacuum leak faulty ECC (Engine Control Computer) ignition coil failing - the ECC will stall the engine if too many misfires are detected. wireset - faulty spark plug wire(s) causing too many misfires. faulty fuel pressure regulator EGR valve faulty
If the engine is misfiring alot, it will **** the resulting unburned fuel out the exhaust pipe, so check for this as well.
Ensure your spark plugs,wires (ignition coil and spark) and your filters (air and fuel) are within 2 years of installation It's erratic at 800 rpm as the engine is cold and they like the 2200 range for 3 minutes before they kick down on their own. Press the pedal twice before inserting your key. The owners manual states depending on the outside temperature, the engine will require more priming. Update if possible.
