Watch battery voltage WHILE it's acting flaky. Easy for me to say, but what about hooking a voltmeter into the cig-lighter/power socket?

 

Had the altenator checked out- according to autozone, it is working fine.

 

I don't know if the 1999 Honda Accord has shift solenoids (2 each) installed. If they do they sit on top of the engine, facing you when you open the hood, where the transmission attaches to the engine. They will have lines (not hoses) going in and out that carry transmission fluid. There will be a connector for each solenoid. Check both connectors but pay attention to the ones with the wiring. On the inside of the connector with the wires make sure the pin does not move. The potting could be bad and the pin is shorting out while driving.

My son had a 1990 Honda Accord some years ago, we took it to the dealer and they changed the computer and shift solenoids and said it was fixed. By the time we got back home the car was not shifting correctly. Started looking at connectors and found a pin loose (it would slide in and out of the connector when pulling on the wire) in the connector and it wasn't mating correctly causing the car not to shift correctly.

 

the ignition is now cutting off when i jiggle the keys (all the lights go on an off on the dash when this is occuring). I know there are mutliplt things you can replace with an ignition- does this sound like the entire unit (key, switch, etc) or just the electrical part? Does anyone have a diagram of this? Have there been any tsb's with detailed directions on this?

 

Replaced the ignition switch. No more problems.
