05 Pontiac Grand Prix (base) stalls randomly while driving.

[Eric Meraz]

I’ve had this problem for a few weeks now, Ive already changed spark plugs and wires, also new fuel pump and filter. I recently removed MAF sensor and throttle body to clean but now it won’t start.

Did you have a check engine light?
Do you have a scan tool?

 

[Eric Meraz]

I don’t have a scan tool but I’ve taken it to a local shop and they said it was for an ECT sensor and no other codes.

 

[melsg5]

So you have a code for an ECT sensor and you or the shop didn't change the sensor?

[Eric Meraz]

Yea I changed it myself but the guy at the shop said that the code would go away after I drove the car a few miles.

 

[melsg5]

What is the code currently?

 

[Eric Meraz]

It’s a PO118

 

[melsg5]

Did you install it leaving the threads bare?
That code can cause issues. Read the this link.
