engine oil hot turn off a/c shaking knocking
I am at my wits end with this car. 2007 chevy impala, 3.9 L
The car had been sitting on blocks in my driveway for 2 months
The vehicle is currently showing a (engine oil hot turn off a/c message.)
The engine is shaking violently and every other time we start it has knock like a rod but different the knock is intermittent it comes and goes. We have replaced, throttle body x2, power steering pump x7, rack and pinion,
crankshaft ps, knock *, tpedalps x3, oilps, a/c, alt, opump, starter, drive belt x2, passengers lower motor mount what could possibly be causing the car to run this way. I give up and do not trust the 2 chevy dealers in my area ... we have a line of mechanics including myself I am just stuck... please help...

Incorrect ignition wire sequence comes to mind. Meaning, spark plug wires are crossed somewhere.

negative on the spark plug wires
Basically I was driving the car, put it into reverse to back into my driveway and the engine oil hot/turn off a/c message came up, it started shaking and running very ruff, I shut the engine off and the car has not left the drive, I am going to do a compression test to confirm if it jumped time, to be honest I have never had so much trouble with a vehicle ever. ..
