On new cars there are several ways to reset the computer. I got a truck I have to turn key on and hit gas 5 times fast and 30 seconds, and then start it. *What always works is to disconnect battery- Negative(black first) then the positive (red side)-(do not let touch sides of metal firewalls). after 30 + seconds hook it back up and it should reset the computer.

put the original radio back in. My guess is whoever installed the radio cut something they should not have.

Hello, I am assuming it is the rear passenger speaker. Please refer to the list below for the wiring of your aftermarket speaker.

Radio Constant 12v+ Wire: Orange
Radio Switched 12v+ Wire: Dark Green
Radio Ground Wire: Black
Radio Illumination Wire: Gray
Stereo Dimmer Wire: Violet/White
Left Front Speaker Positive Wire (+): Tan
Left Front Speaker Negative Wire (-): Gray
Right Front Speaker Positive Wire (+): Light Green
Right Front Speaker Negative Wire (-): Dark Green
Left Rear Speaker Positive Wire (+): Brown
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Dark Blue
Right Rear Speaker Negative Wire (-): Light Blue

It actually might be better to just disconnect the negative side of the battery and then bleed the pressure off manually, that is how we do it at my shop.

fun fun fun.

You can connect the - or negative to the negative on the battery or whereever it will reach on the engine or body. The engine and battery are preferable. Just be sure it makes good contact, bare shiny metal is best, a quick rub with a file or sandpaper before you hook up is a good idea. Watch the guage on the charger as youwiggle the charger cables to see if it moves higher. If it does, clean up your contact points. Hope this helps.

no in the gas tank, have to replace the hole sending unit i was pissed off to.

It could be your alternator. If the battery light is on thats usualy what thats a sign of and areason it may still run and not accelarate is your battery has enough juice to start it, but not to keep it running. If this is the case try hooking jumper cables to it and seeing if you can throttle it up with them hooked up.
