Ac on dying out
Hello got a 2007 2.2 when I have the ac on and slow down to stop the car will die out .. have to restart all is fine .. I have clean the throttle body maf sensor , new air filter so I’m wondering if it is vapor lock ? When ac off it does not do it so just wondering if it got something to do with Ivac ? Also no check engine light on at all ..

I see I need to explain.
The A/C compressor has bearings. The bearings wear out and bind. When the engine speed is high it can overcome the resistance, when it is low the compressor acts as a brake.
When you turn the A/C off the clutch is freewheeling, so the bearing is not turning.

I will say I had a Cat 4116 mechanic engine in a truck that was towed into the shop and it was said the engine was seized. And yes you could not bar the engine over, one way or the other.
The tensioner was seized for the serpentine belt and that was the total problem.
It amazed me that the belt could stop the engine when the tensioner was bad.
So is the tensioner starting to go bad on his engine?

Bad torque converter (if it's "locked" up) would drag the engine down all the time, a.k.a. no acceleration.
