    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

Transmission is either low in fluid or has gone out. Crank it up and let it warm up to operating temp then pull emergency brake and put car in neutral. Check fluid to make sure it's full and not a dark color. If it's real dark then the trans is burnt up.

My automatic Corolla AE110 vibrates when i stop in gear but it stops as soon as i start moving or when i put it in neutral.What can i do? Please help


It seems that your engine is tuned to very low idle revs, hitting the low resonant frequency of the car at tickover. When in neutral or revving up (moving), the engine stops shaking.
You can have it tuned to be slightly higher so it won't idle so bad, but you'll lose a little bit of fuel efficiency in the bargain.
Alternatively, just shift to neutral - free and easy.

I have a 1990 olds 88 royale 3.8 Just replaced the fuel pump, and both fuel filter. A week later coming to a stop the car dies. It's seems every time I approach a stop and get under 25 mph it dies....


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.
