Yes I've had codes and thats what leads me to replace all these sensors. It literally just cuts off while im driving. And yes some times I do have to let off the gas in order for it to shift.

Usually if you have to let off the gas for it to shift it's a clogged cat. So what are the exact code number's you have.

Codes we P1780, P0128, P0727, p0335, p0102, p0421, and I also replaced the mass airflow sensor. So can the clogged cat converter cause it to shut down while driving too?

The clogged convertor can cause a stalling lack of power and make you have to let off the gas to make the transmission shift. The code P0421 is a cat code the p0128 is usually a bad thermostat. The P1780 is a torque reduction command. The P0727 is ENGINE SPEED CIRCUIT - NO SIGNAL. The code P0335 is CKP SENSOR CIRCUIT your crankshaft sensor. The p0102 is MAF SENSOR CIRCUIT LOW VOLTAGE mass airflow sensor. So did you ever clear the code's after you replaced all those part's?

Yes the codes were cleared but the car broke down again, then comes the service engine light on again have not had any diagnostic yet just confused and dont kno if I need to put any more money into this vehicle, as parts and labor can become very expensive for this particular car. These were all codes from auto zone

So when shuts off while driving does it restart right away or do you have to wait for it to start.

I have to wait maybe thirty minutes or so then it runs for about 20 minutes and shuts off again.
