I have a 2005 Dodge Stratus. I recently took it in for an oil change and the tech left a hose off after checking the air filter. I have had it back to the shop several times since for high idol and engine light problems. They are now telling me that there is an issue with the idol sensor and the cam position sensor an that it's unrelated to the hose being left off. I had no problems prior to taking the car to them. Could the problems be completely unrelated or are they trying to pull a fast one?

 

Welcome to DF
Did you have this problem before? Because if you have high idle, you may have a vacuum leak. And do you know the code for the cam sensor?
