My gmc envoy xl 2004 wont start and before this it would cut out like it was running out of gas but always had gas also the dash board light will start flashing like crazy on there own


The first thing I would suspect is the ignition switch, these have been known to cause all kinds of problems when they go bad. If you are handy, it can be replaced by a DIYer. Go to www.trailvoy.com and do a search on ignition switch replacement, for instructions on how to do it.

2004 Envoy xl stalls when making turns


this is caused by slow engine idle speed, do the procedure below.
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
