Subject: Re: Any recommendations on spark plugs? by Eagle223usa on 2022/8/26 12:04:10 Well, I pulled the codes and I think I found my miss. I pulled codes H33 and H34, IIRC. Map high and Map low. I ordered a new one from Rock auto, along with the connector, which disintegrated when I tried to disconnect it. The check engine light was not illuminated. A bad Map can cause a misfire due to improper fuel being delivered. I hope this cures the problem. |
