    The check engine light comes on and says low output tps. I replace the tps twice now. After clearing code the engine light goes out until I shut the engine off. Then when I start it again the light goes on. It never comes on until I shut the car off then restart it. The light never comes on after I first clear the code. It is always after I shut it off and start it again

When the check engine light blinks that means you have a misfire in a cylinder

Here are some of the causes 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.

Idle air control


all the sudden the check engine light came on and it started to idle funny and dying at stops. I had a diagnostic done on it and changed out the idle air control valve but it doent seem any different. and the check engine light is still throwing the same code. we adjusted the idle up so i could drive it with out it dying but it is still acting funny.
