1994 honda accord ex with the 4 cylinder v-tec It starts missing at around 1900 rpm under load then goes away at about 2100. Pulled plugs and the #3 plug was fouled.
Did a complete tune up plugs wires cap rotor etc. Checked timing good. Pulled intake apart and cleaned out replaced pcv valve it was sticking improved a little but still misses. It does not miss when reved to 1900 rpm with no load. Checked egr valve with vac works but the miss goes away when vacum line to egr valve is pulled and plugged. No codes are logged. I am ready to try replacing the egr valve but am not really sure if this is the problem. Any insight? Possibly bad distributor?

Try using a manual hand pump to apply vaccum to the egr valve, if it functions properly and the missing goes away replace the vaccum line, if not clean the egr valve ports, and if still no help replace.

Also clean the MAF sensor.

First check for vaccum leaks. Use a can of brake cleaner/carb cleaner and slowly spray the vaccum lines and around the intake manifold gasket with the vehicle running, if idle is changed you have foudn a leak. Also perform a compression test on the #3 cylinder.

Already checked for vac leaks and compression is good in the #3 cyl.

Put #3 in TDC and check to see if the distributor rotor is pointed at the #3 spark wire, if it is then its not the distributor.

Check the injector, maybe its not getting pulse at that bandwith.
