Hello and thank you for using Just Answer
does it ever stall while driving? or only at stops? idle speed?
when it stalls does it start right back up?
So it stall when in gear but not nuetral
I am attaching a list of things to check... check the throttle plate is clean first. and check for cracks in the air intake tube.
Stalls in drive or reverse
there is also some cases of the ECU connector causing a bad connection and a stalling
you want to check out all these items
let me know what you find and if you need more help
Please ignore the last message I had some technical problems with the page
Throttle Body - Carbon build up on the throttle plate or any other cause of low base idle speed can cause the engine to stall when the transmission is shifted into drive or reverse. Idle Air Control (IAC) Valve - A dirty or defective IAC valve can cause the engine to stall when the transmission is shifted into drive or reverse. NOTE: May also be referred to as a bypass air control (BAC) valve. Overlooked Causes Wiring Harness - Engine movement can cause the wiring to rub through into a component and short out or cause broken wiring or poor connections to open causing the engine to stall when the transmission is shifted into drive or reverse. Grounds - Due to engine movement, loose engine control module (ECM) grounds located on the engine can cause the engine to stall when the transmission is shifted into drive or reverse. Intake Air Boot - A crack or split in the intake air boot can open up with engine movement causing the engine to stall when the transmission is shifted into drive or reverse.
There have been cases of the ECU harness connector not making a good connection causing this type of stalling
Click here to view the report
run the engine while moving the connector and see if you can get it to stall
On the right side kick panel is listed as a cruise control module
the ECU says it is under the left side of dash
unfortunately I do not have a graphic of it's location
the ECU has 4 seperate connectors that go into it
let me know if you locate it
