2005 Aztek. Intermittent stalling problem. Most of the time
Intermittent stalling problem. Most of the time runs great. Sometimes (maybe once a week) it will start funny (like the starter wants to stay engaged for a couple seconds after I let go of the key) and then it will idle rough. Then while driving it will not have as much power. At stops it will idle rough and stall as soon as I step on the gas. Will start back up immediately but will continue to run rough. If I shut the engine off and leave it off 5-10 minutes it will start like normal and run fine. Does not seem to matter if it is wet or dry out. … read more
