Its only noticable down low, but if u rev it up it goes away. I was told that there is no fuel filter in this car, the plugs look fine, the odds of it being a coil is slim because every cl has one and every cl is missfiring. It looks to have a new rotor on it........ any ideas? Thats the only code this car is throwing btw

I have a 99 v6 accord and mine was doing that one time but it was the plug wires. They were all burnt up and crispy.

What is the MAP voltage at hot idle? What is the ST fuel trim at hot idle?

Being a v6 it could have tight exhaust valves.

map read like 4.7ish volts. This car is a bitch to diagnos. I still dunno whats causing this. Maybe the plugs arent gapped properly

I doubt the MAP is 4.7 volts. At hot idle it should be around .88 volts. If it were 4.7 volts it probably wouldn't run at all.

If MAP is higher than .88, say around .95 or above 1.0 I would perform a valve adjustment.

You should bump after you check valve adjustment.
