I have a 2007 Cobalt LT coupe, fully stocked except for 5% tint all over and konig wheels.
For the past few months the engine check light came on for a couple of days then off for weeks then back on for days, off weeks, so forth until recently something was a little different so I decided to go and get the diagnostic codes.
Then I decided to go to a friend's friend's shop. They checked the spark plugs, among other things and told me to buy a new thermostat and camshaft position sensor and come back, they will replace them and problem will be solved. So I did.
As I left the shop my car did not start until the 3rd try. Happens every time I start. Returned to the shop with parts 2 days later.
Thermostat sensor replaced, and yes problem solved.
Prior purchasing the part, I looked online to find out the price for the part at O'Reillys; I saw "parts needed for this vehicle- 2" but I was told to get one. Camshaft position sensor replaced, codes erased and I was off on my way, STILL with the starting problem.
I went back this morning and they said they will take care of it tomorrow, suspecting that the camshaft position sensor is defective.
My starting car problem began when they removed the spark plugs and put them back. I am thinking, check the spark plugs? I dont have ANY tools.
Secondly, is there one or TWO camshaft position sensor on 2007 Cobalt LT 2.2L?
Third, if the camshaft sensor is replaced and the problem persists- what do I do next? I am going on a cross country roadtrip on June 2nd from Arizona.
