Low oil pressure comes on even tho it is full of oil. Engine stalls but restarts easily. Take to my mechanic tomorrow.
Replaced cam and both crankshaft position sensors and still have the issue. GM has been made aware of losing ALL power while driving at highway speeds and they don't have a solution themselves.
engine would stall and catch back or would restart while driving down highway. Sometimes hard to start. Replaced both upper and lower crankshaft sensors. Worked fine after that.
Mechanic had my car for a week, replaced both crankshaft position sensors, new spark plugs, oil change, tire rotation $836.00. It stalled 2 times driving home from the garage. Called the garage, they told me to bring it back on monday....but they didn't sound very reassuring......sigh
check engine light came on it was the crankshaft position sensor B I had to take the exhaust manifold off to get to it i replaced both sensors B is on top ,once you do it have the check engine light cleared and you'll be kool
