it drives fine down the road when my foot is into the gas pedal and then stalls if i let up on the gas(sometimes). no codes on the computer at all. Engine type: 2.4L L4 DOHC 16V
GMC Mechanic: Gary, ASE Certified Technician replied 2 years ago
Thank you for that information
most of these kind of issues with no codes being set are usually one of 2 simple things
the throttle body is dirty or the MAF is dirty
the best action to take is to pick up a can of carburetor cleaner and MAF spray cleaner
pull out the MAF in the air cleaner and clean it good with MAF spray cleaner then remove the hose on the throttle body on the engine from the air cleaner and clean out the throttle body with the carb cleaner making it spotless and make sure you do NOT pry open the throttle body butter fly
once both are cleaned re install everything and take it for a good ride
this should correct this issue you are having
