So, I have just started to get a p0340 code on my 2004 Neon SE. I know it's a camshaft position sensor code, but I think it's something else that's throwing it. I changed my air filter last week and then the code started throwing with the CEL. For clarity, I do have an ignition interlock through intoxalock. But, I reset my computer the old school way by using Scotty Kilmers video, and my car drove like it was brand new yesterday and today. No jerking, no stalling, no CEL. Just now I went to the gas station and it threw the code again, and started the weird jerking stuff. So, I'm wondering if anyone has any advice on what I should do? I'm unemployed and have 2 interviews this week, and need my car to be running.
