My sister went out after getting back from the store and vehicle was fine and then went to leave again and when she started it, it sounds like a desiel! I used some motor flush, changed her oil and plugs and changed the camshaft position sensor to since she did have that code and still sounds like a desiel??? Checked the timing and it’s fine?

Ok and is it asking to check the wires on the sensor side or wiring harness side
Customer reply replied 3 months ago
Ya that would require time to jack the vehicle up, remove the sensor and that’s isn’t just a quick thing to test
Customer reply replied 3 months ago
Crank sensor will not cause it to run like a diesel though right?
Customer reply replied 3 months ago
it’s not wanting to stall on me or not start

Located right on top of the driver side front motor beside the oil dipstick
Cadillac Mechanic: David Craig, Auto Mechanic replied 3 months ago

I wouldn't buy a screw from AutoZone. I recommend an OEM replacement sensor, but as far as the dieseling sound it could be a lot of things but my bet if a worn timing belt

Ask Your Own Cadillac Question
Customer reply replied 3 months ago
The timing belt does need replaced I took the top of the cover loose and noticed some dry rotting cracks going from side to side around the belt, and a buddy of mine told me if the timing belt tensioner wears put it can make the valve rattling sounds, where is the vvt solenoid located? If the timing belt is wore out would it cause the diesel sound out of nowhere after running perfectly and then coming back out to the vehicle five minutes later to leave and started it up and has been making that sound ever since?
Customer reply replied 3 months ago
When I replace the spark plugs I also check to see if there was any play in the pistons and all is tight
Customer reply replied 3 months ago
This has costed me 2 hrs to check two sensors that I already knew was good and replaced man? I need to know what can cause this thing to sound like a diesel/valves rattling sound out of no where? It has good oil pressure, fresh oil change, I even added Lucas oil stabilizer ....
Customer reply replied 3 months ago
Even replaced the fuel filter with new plugs because I noticed a slight lope in motor at idle
Cadillac Mechanic: David Craig, Auto Mechanic replied 3 months ago

apparently, we are going to disagree on this. it's a worn out belt. if it's cracked from dry rotting, its worn out. it took 2 hours because you didn't know how to use a meter. you have a worn belt or worn cam lobes. good luck

Ask Your Own Cadillac Question
Customer reply replied 3 months ago
I think I will just get a new timing belt and Idler/tensioner kit and go from there
