While at a stop light the car starts acting like it’s going to cut off, does this sputtering, sometimes I have to turn it off, so it doesn’t shut off, it actually has cut off while running. I took it to two separate mechanics, they both said they fixed the sputtering, but have not, these are the parts that were replaced. Valve cover gasket, changed twice, intake manifold, water pump, serpentine belt, upstream O2 sensor, spark plugs, MAF, coil pack, intake hose, PCV valve tubing, coolant tank, the throttle body was cleaned.

Hi,

Wow, it sounds like they are all over the place. Presently, are there any diagnostic trouble codes present? If you aren't sure, I would recommend going to a local parts store and have them scan it for you. Places like AutoZone do it free of charge for their customers.

Here is a link that shows what needs to be done:

I you have already had this done, let me know what codes are present. As far as the issue, it could be a number of things causing this to happen. The codes will help point us in the right direction.

Let me know.

Joe.

They are all over the place! And no, there is no check engine light coming on, the only thing that comes up on the dash is service stabili track and traction control.

Hello,

Just to add to the issue
Warning on dash for service stabili track and traction control are usually caused by the ABS/ESP module receiving implausible signals from the ECM, engine control module.
Fault code U0401 is usually present in the ABS module when scanned using a suitable diagnostic tool

As previously suggested have the vehicle scanned for fault codes, some engine fault codes do not bring on check engine light

If possible, also have the live data read in the ECM for LTFT, Long Term Fuel Trim.
This is a learned value, and it should range around 0%, an increased value usually indicates a secondary air leak as the ECM is trying to counteract by adding extra fuel. This could cause this behavior and the dash warning lights.

Well I took it back to the mechanic that originally worked on it because it was getting worse. He says there was a wire touching the engine. I drove it home and so far, is doing alright except the check engine light is on throwing the code p0132 and still has the service stabili trak and traction control.

Hello,

I suggest to still have the vehicle scanned for codes in other control modules, especially the ABS module
A fault with the mixture control could set the traction control light

P0132 - HO2S Circuit High Voltage Sensor 1
The ECM detects that the heated Oxygen Sensor (HO2S) voltage is greater than 1 050 mV for greater than 10 s.

Ignition OFF, disconnect the scan tool and wait 60 s to ensure all modules are powered down.
Disconnect the Heated Oxygen Sensor 1
Measure for less than 5 ohm resistance between Heated Oxygen Sensor 1 low signal circuit terminal 3 and ground.
If more than the specified range, test the appropriate Heated Oxygen Sensor 1 low signal circuit for an open/high resistance. If the circuit tests normal, consider a possible issue with the Engine Control Module.
Ignition ON, test for 1.5-2.1 V between the Heated Oxygen Sensor 1 signal circuit terminal 4 and ground.

If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, consider a possible issue with the Engine Control Module.
If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, consider a possible issue with the Engine Control Module.
Install a 3 A fused bridging wire between the Heated Oxygen Sensor 1 signal circuit terminal 4 and the low reference circuit terminal 3 of the appropriate Heated Oxygen Sensor 1. Engine running, verify the scan tool HO2S 1 parameter is less than 60 mV.
If greater than the specified value, consider a possible issue with the Engine Control Module.

Verify none of the following conditions exist:
Water intrusion in the HO2S harness connector
Low or high fuel system pressure
Fuel that is contaminated
Fuel saturation of the evaporative emission (EVAP) canister
Exhaust leaks near the HO2S
Engine vacuum leaks
If you find any of the above conditions, repair as necessary.

If all circuits test normal, replace the Heated Oxygen Sensor 1
