After all that work yesterday I knew I would find a solution soon because I was running out of things to check. Today I went to the parts store and picked up some new NGK spark plugs, NGK ignition wires, distributor cap and rotor, fuel filter and a radiator cap since my old one disintegrated yesterday. I started by changing the plugs and then started the engine and guess what to my surprise BAAM! engine runs fine, so it was a fauled up plug that was causing all these issues. I still changed the fuel filter, iginition wires and distributor cap and rotor as it had to be done in the near future anyways. The spark plugs I got are the NGK ZFR5J-11 which seem to work really well with this engine. It runs smoth now and has lots of power and I’m not even activating the VTEC yet! The only thing I have left is to wire up the VTEC and bolt up the front bottom engine cover but thats not even an issue.
