Why does the car slow or stall at 45 or less, ICM?

I have spent $630.00 at Precision Tune and the problem wasn't fixed. Ready to pull hair out! Slows down or stalls at different intervals when going 45 or less.

Hi,

What was done at Precision Tune? Also, is the check engine light staying on while the engine is running? Does it ever stall above 45 MPH? Are there any diagnostic trouble codes that are indicated on the receipt from the shop?

Let me know if it stalls when your foot is off the accelerator pedal or if it happens when you are accelerating. Additionally, let me know if there are any odd sounds or odors from the vehicle is running, and if there is any smoke from the exhaust.

Take care,

Joe
