Have a p0130 CEL I’ve been chasing. I’ve replaced the exhaust manifolds and gaskets to get rid of a small exhaust leak, and both O2 sensors. p0130 and p0133 went away for a while, but p0130 has been coming back regularly now.
I was replacing the vacuum lines and noticed the EGR valve looks really bad.
I had replaced the melted EGR modulator when it had melted maybe a year ago, but figured the valve was fine bc I wasn’t getting the p0401 code.
From when the EGR modulator had melted.
I had replaced the cats and O2 sensors 2 years ago. I used denso sensors previously, this time used NTK since I read that’s what OEM was.
Also replacing the Carbon canister hoses since they’re in bad shape and considering changing the canister itself with a GM, based on another thread.
I’m planning to replace the EGR valve bc its clearly in bad shape. Is there something else I should be looking into?
