    if you live in the states... drop into autozone and have them check the codes on it... it's free and would give you a better idea what needs to be done

When you say looses power do you mean even the dash lights? If not you should consider replacing the cam sensor. When it goes bad it seems like the batt is dying because of mis-timing of the spark. And it also feels like you have turned the key off while driving sometimes.

08 Chevy Cobalt wont start. Battery is good.?


Generally speaking, if the starter was dead it would not jump start.
Sounds like the key switch or the neutral safety switch.
You would need to know if the starter has power when the key is in the start position.

It could be the vacuum modulator on your auto transmission, sometimes when vacuum hoses fail,split or whatever, they can suck up impurities causing other downstream items to fail. Also check mechanical linkage form shifter in cabin to transmission gear selector arm. If jumps were happening these might have worked loose. Best of luck!

Transmition is slipping


2nd gear is the fail safe gear, that car will run in second if there is a transmission problem to get you to your local repair shop, sound like you need a transmission you can check the fluid level and try adding a product called LUCAS transmission conditioner to try and help revitalize your transmission, sometimes this works.

Is there a way i can make my pop up lights on my 91 firebird stay up


sounds like the connecting rod to the drivers side is broken loose from mount, can try to reconnect rod, actuator on passengers side is not working possibly mmm i think those were vacuum line run so check vacuum tube. If mount is broken possible epoxy together. both fixes shouldn't be too bad and correct running lights, a Chilton or Hayes repair manual would help you with diagrams and instructions, and any of the fire bird forums would be able to give you more help. Good luck on fixing up that old bird, hope you have a v-8.

87 thunderbird some times starts but quits when put into geer


check your contact points are set correctly, or may even be burned , if so replace them , its a comon thing if the contact points are badly set ,when you put the car in gear it will stall or wont idle , i had a 67 t/bird landau that did exactly the same , , turning off the highway was a night mare ,i had to keep the accelerator pressed while i braked , otherwise it would stop and then i would have no steering ,very annoying and very dangerous
