2003 acura cl type s 6spd

I got the following codes
P0300
P0301
P0302
P0303
P0304
P0305
P0306
P1399 pending

At 95K miles the timing belt gear and waterpump was done, Valves adjusted, and spark plugs replaced. Car currently has 109k miles. Is there a certain thing that would cause all these codes?

Thanks

Misfires. Bad gas? Incorrect spark plugs?

hehe i have same problem and i found out that my runner is broken not sure if that is related to this problem but as soon as i fix this problem i will let you know...

P1399 might be dirty EGR or misadjusted valves - clean egr with carb cleaner replace sparkplugs then coilpacks if that doesnt help check valve clearance again and redo if necessary

this is my broken runner car is still running and right after xmas i will pick up new runners and swap them out...

i would check for leaks maybe one of gaskets is worn...

injector cleaner will help as well

i would do first:
1) Clean EGR valve all the passages under the IM plate and the passage that goes to the EGR valve with matal hanger... when you are there check for hair line cracks like mine on the runners



2) get some injector cleaner (seafoam, lucas, whatever you like)

3) change spark plugs for oem NGK iridium

4) replace all the coilpacks

5) check ground wires for rust, loose

6) check the valve clearance once again if necessary do it again

7) not sure did i missed something ?


check and make sure all the gaskets were installed correctly

I thought back a bit to when the light first came on and that was when I started getting gas at a different station. Went back to my original gas station and the light(s) went out and haven't been back.

Guess it was crummy gas.
