So I have a 96 accord with lx body and a dx engine I keep getting check engine light for cylinder 2 misfire cylinder 4 misfire and random misfire I have replaced the following with no avail egr valve, spark plugs, plug wires, ecu, main relay, valve cover gasket, distributor with cap and rotor, map sensor, idle air control valve, ignition switch, coil, air filter for cold air intake, fuel pressure regulator, oil pressure switch and I have also cleaned egr passages had a compression test done was told all four cylinders where around 150 psi I need help figuring this out driving me crazy so can people please give me there thoughts

 

What code/s (Pnnnn) were set specifically and any codes in addition to miss codes?

Is miss present all the time on 2 & 4 or intermittent?

A leakdown test is indicated to understand if anything is amiss in cylinders 2 & 4, intake or exhaust valve leak, or compression leak. See following link for one of many youtube videos on subject.

Suggest also checking long term fuel trim (obd2 scanner) to see if there is an indication of fuel injector blockaage (high + LTFT). As FI is blocked, LTFT is added to maintain correct air/fuel ratio. This can lead to missing in some cases.

good luck
