98 Civic LX - P1399 and P0303
I too had the P1399 and a P0303 code after having work done on distributor. CEL came on 20 minutes after I left mechanics. It blinked for a short time and then just stayed on. I was told not to worry about it so that's what I did until it failed emissions because of the light. Well I know now to never ignore the check engine light. To try and correct this,I had the head gasket, plugs and wires, battery, icm, Ignition Switch, distributor cap, AC Compressor RMFD w/cltch, thermal expansion valve, and receiver drier replaced. I also had timing adjusted but after all this the check engine light is still on with a cylinder 3 misfire. I had another mechanic tell me I needed a whole new engine!! This makes no sense to me...nor can I afford to do that. Can someone please give me some advice on where to go from here? Thanks!

How did you fix this? I have a 1998 Honda Civic DX that started with a CEL. Checked the codes and got P302 and P1399. Started troubleshooting by check spark plugs and then swapping wires. When I changed the wires between #1 and #2 the troubles spread to P300, P301, P302, P303, and P1399. Thought I was going to have a very bad day. Then checked the compression and everyone of them was over 180 except #2 was 145.
Car would start but idle very roughly. When driving it wouldn't handle any uphill slopes or hills well and would almost stop. As soon as the hill leveled out it would accelerate again.
Then put everything back the original way and went back to P302 and P1399.
Headed to auto zone and bought new plugs and wires. Put them in and everything works excellently. All codes gone and the power is back.
