code p1000

[demontang]

So Ive been getting this code p1000 and dont know why. Ive looked it up and done the driving cycle but still get it. I just tore down the whole top of my motor and check all the conections, vac lines, and cleaned everything I could. I got it to pop up the p1100 code now which Im looking into but it still gives me the p1000

If the drive cycle hasn't cleared the p1000 then something isnt ready.....you'll need to invest in a readiness reader or get those codes read at an emission testing site or dealer to find the issue....
