    2010 Cobalt LT flashing driving lights

    If this car was in front end accident, your problem is most likely in the front. I would check the ground wire mounted under the left front headlight(big wire), ground wire under the coolant tank. And ground wire on the radiator core support behind left head light. If it was hit hard, or left...

    Can't Diagnose 65mph Shake

    You must be using the wrong three shops if they can't figure out your shake. Find a new place to take it. Or take it back to the shop that fixed it when the shake first started and shame them into FIXING it correctly. Maybe even try a GM dealership. There's not much to these cars, sounds like...

    Performance problem

    I would check spark plug boots. Coil pack. Ground wires on transmission by starter. And get a good scanner that has live data so you can watch the misfire count while driving.

    How to Clean Sunroof Drains?

    Open the roof all the way or locate the torx screws that remove the glass all together. There are four drains, they are located in the corners. I like to use compressed air to blow them out, I stick a plastic tube over a blow gun and push it in about six inches as to not blow the connection...

    Bmw

    The body control module is locating under the radio, the wiring goes from there to the rear, my best guess is that who ever removed the dash, let it rest on the wiring, since it's heavy. There are also some ground wires that have to come off to remove the heater box from the dash. I would remove...

    Remote starter bypass

    You can find a local tuner guru, pay gm to unlock your vin, and turn the programing for the anti-theft off. Or, Cut the head of the key off, glue in to the inside off the plastic pieces around the steering column close to the ignition switch. On the wiring, you can find a local salvage...

    Another Misfire issue

    All the wiring connectors on the cobalt come apart. If you remove the purple part off the inside of the coil connector, you will see that little plastic fingers hold the wires in place. Push the finger back and gently pull on the wire. Then get a another wire from another harness, it don't have...

    Misfire issue

    There's a large ground wire located under the driver sides side headlight, you have to remove the headlight and the headlight bucket. Follow it back to the transmission, there it connects to the grounds that are known to be a problem on a bell housing bolt. There's about seven or eight ground...

    2007 Problems. Could it be starter?

    I thought that was a legitimate question. Since the high voltage battery in a Pruis is about 2 hundred volts. But seriously. Where did you hook the jumper cables too? The fuse block, or the battery in the trunk? There is a fuse in the trunk by the battery. 60 amp I believe. Was your car running...

    Did you jump a Prius?

    Misfire issue

    I reread the entire thread, in your first post you stated that the car shuts off after 30 minutes. Is it always 30 minutes? Do you have any codes that are U1000? Do you live in a wet area, by salt water? Has the car been in an accident? Flood? There is a piece to this puzzle that is missing. Who...

    Misfire issue

    So you have a 2006 Cobalt 2.2l with 57k, with a miss on 1 & 3, you changed plugs, you swapped injectors, you replaced the coil pack, and verified compression. How long have you owned it? When did it start missing? Was the coil pack new or used. Could be two bad ones, seems not likely...

    Installed new clutch; not getting enough pedal :-(

    I don't think the machine shop could take enough off for you to not be able to disengage the clutch. You should check the rod leaving out of the clutch pedal. The rod should move right away. There's a plastic piece in there that could be damaged allowing the pedal to move before moving the...

    Misfire issue

    You can check the timing by simply pulling off the valve cover. Should take less then 20 minutes. I have seen many jump timing, usually the top chain guide is cut clean off, or the tension-er has failed. I have seen a few chipped valves on the #1 cylinder. Timing is only one you can fix, as a...

    You've changed a lot of parts. Have you checked compression and your timing chain?

    Filling 2009 LT Transmission

    Automatic transmission, I'm assuming. The file hole is on top, between engine and fuse box, usually red in color. There's a 11mm bolted in level check on the passenger side, about 3 inch from where the passenger side axle is, between the transmission and engine, about level with the axle. Start...

    VERY rough cold start - Opinions Please?

    I can't remember a single time a fuel filter ever solved a problem. I have pulled so many gas tanks, changed so many fuel pumps, and there always clean like new since most tanks are now plastic. And most gas stations use better filters then you'll find in and under the car.

    Wipers going nuts!

    I got that part. That's why I said replace the whole wiper assembly as a unit. The unit is broken, there's no other explanation if the wiper leaves the window area, and the arms are on correctly. Simple geometry. One of the studs that hold the arms is pivoting, allowing the arm to travel to far.

    Pontiac g5 gt

    Don't waste your time or money modifying the 2.4l. Sell the G5 and buy 2008 and up Cobalt SS with the turbo motor already in it. When you figure in the cost of modifying the motor, tuning, car down time, and breaking stuff, you'll understand my reasoning. If you want to throw your money away...

    Wipers going nuts!

    Replace the whole wiper unit. It is broken somewhere. The wiper should not leave the window if it's starts at the bottom. The BCM and fuses and relays don't control the geometry of the swipe. The wiper unit is broken. Should be able to get a used one cheap. $20 to $50. Pretty easy to change...

    VERY rough cold start - Opinions Please?

    Try turning the key on three or four times before cranking it over. This will help build fuel pressure.

    Clutch Pedal Wear, ION

    Just wanted to put this out there. Some costumers brought in a 04 Saturn Ion with a 5-speed manual, complaining that the transmission or clutch was going bad. Had to push the pedal all the way to the floor, to switch gears. So I test drove and in fact there seemed to be a serious problem with...

    Exhaust camshaft sensor code

    There's no sensor on the exhaust cam shaft(there's one on the intake). There is a solenoid for the exhaust cam(part of the variable timing), it's very easy to change and costs about $40. Both intake and exhaust solenoids are on top of the engine in the valve cover by the number 1 spark plug. The...

    Wipers going nuts!

    Take the wipers arms off, bump the lever and wait for the motor to turn and stop, put the wiper arms back on. I'm thinking you have the arms out of alignment.

    Coolant level dropping without a leak

    Depending on how much coolant you are losing, it can only be going one of two places. Either leaking outside or inside. Here's what I would do. Buy or borrow a coolant system pressure tester, and pump the system up to 15 pounds. Let it set for a few minutes, and look for coolant under the...
