stalling

Asked by Guru8C5G3 Dec 30, 2019 at 01:08 PM about the 2006 GMC Envoy

Question type: Maintenance & Repair

i went through a puddle and since then the vehicle will start but you have to keep on the gas at all times when driving or it will quit.  I replaced a coil and a sensor that had a crack in it but it still keeps stalling, could it be something electrical or the onstar system

Make sure battery has a full charge and connections all good. Check for applicable trouble codes, manufacturer specific codes as well as po codes. I was wondering about tac codes/ throttle actuator control. The pcm controls the throttle. No linkage cable from gas pedal to throttle body, operates electronically. Maybe the tac needs to relearn? Just my opinion.

19000 things can cause an issue.need to retrieve codes. Auto zone usually does that free if you have no other options.
