Default Please help!!! I cant figure it out.

Sometimes I'll crank my ranger and it will run really rough then it will straighten up then I'll go down the road and it'll do it again then straighten up but it will never actually break down. I've replaced fuel pump, plugs, wires. It throws two codes, p1451 and p0443 but it has had those codes since I put air ride on which was over a year ago. I've driven it all over the state of mississippi and its just now doing it. I washed the motor off a few weeks ago and it did it a little then but now it's progressively worse. Could it be the coil pack?

looking up those fault codes says it has to do with your Evap control valve...have you looked there?

I have. I replaced the purge valve under the hood with a used one. It got a little better but it still does it.
