Default Check engine light and traction off light on - hissing sound

i don't know what'* up with this

it was running rough and missing the other day so i took it to a shop and got my MAF cleaned which did the trick when i picked it up today, and on the way to work, it started making this hissing noise, so i got out, and looked at the oil filler cap, took it off, the engine died down almost then it went to about 600-700 rpm.. and i put it back on and it'* hissing

the check engine and traction control keeps coming back on and i don't have a clue

please someone help ?

Change your PCV valve (don't lose the o-rings).

Get a scan for the check engine light.

Your traction will likely be an expensive fix. For the time being, make sure the wheels speed sensors behind each hub is connected and corrosion free.

i just went outside and started her up and the lights both went off



could this be a normal intermittent cause for the Check Engine light to engage?

It'* tough to hear the hissing in that clip.

Definitely start with replacing the PCV. About $5 for a new one.

On the passenger side of the upper intake manifold. All the way at the end. Within the cavity, there are two o-rings that keep it seated in place.
