Why does it occasionally experience complete, temporary loss of electric when coming to stop?

See if you can get a socket to tighten up the bolts. If not , a temporary fix may be to use a bottle of oil leak fix from an auto parts store. There is something in the liquid which causes the gasket to swell and slow down or stop oil leaks. Ive heard though that long term, this stuff can cause the gasket to eventually fail completely and will have to be changed anyway.

Alternator would be the first part that I would suspect to be the problem. The battery, then an intermittent short in the electrical wiring would be the next place I would check out. Also check to make sure that the wires are securely tight on the battery too.

simple test
ut the hand brake on and start the car
idling ok --good --apply the foot brake-- idling bad --replace the brake booster
check for other vacuum leaks including transmission actuator hose , dash vent controls hoses

Try cleaning the IAC valve

Hello, I have 1996 Ciera with rebuilt engine pretty new, also fuel filter and fuel pump replaced but I have a problem, the car starts and runs well cold but once car has been running for a few hours, either stopping or coming to a stop it starts to idle roughly and has come to a stop at different occasions. Check engine light does come on and off occasionally. Can you help?

The MAF sensor is the likely problem. Ca be clraned w/crc electrical cleaner only. Do not touch , rub,or use compressed air to clean or dry. It's located in the intake duct in one of the metal sections. The plug and wires will give it away. Good Luck-Ned-

open cercuit on crankshaft sensor..

have your idle air control solenoid cleaned out!

think this a problem for dealer mechanic with product knowledge,because all lights coming on then loss of power sounds like it could be an ECU fault being triggered by a sensor,or just a component in the ECU breaking down .It would need the computer connecting then running till fault shows up .sorry i couldnt give an instant fix

Check the trans fluid for quantity and color. If it is not a good red color, try having it changed and get the filter cleaned. If that looks okay, you may have a bad shift solenoid. Look for leaks around the trans case. Leaks on top around the solenoid are a sign that it is going bad.
