Drove car, all fine. Parked for 30-45 mins. Started car, in gear, jerking with loss of power. Auto outline warning light with wrench shows. This has happened 3 times, two mechanics, no fix.

I put a new motor in my car but took the whole top of the motor and put it on the one I put in. All the electronics that was on my old engine was switched to the one in it now. The car will start but idles up and down, give it fuel and it sounds like it wants to quit. I was told I need to flash the ECM. If the electrical is all the original hooking up this new motor, why do I need to have it flashed?

When I start the engine it runs fine at first while cool. If you shut if off after running it for 10-15 minutes, the dash lights come on and off, the gauges work and stop working, and when you push the gas pedal it takes it a few seconds to rev up and when it does it only goes to half rev? I blew the engine in the car after I bought it and have recently put another engine in it. Checked over compression, fuel pressure, sensors, wires all connected, grounds were cleaned up before being put on, checked exhaust. I'm exhausted trying to figure out why it will start and run say first start in the am but I haven't driven it anywhere due to if I shut it off when it's warm, I restart it and it's all f***Ed.....help me please

the bright light ico is on its my mother in laws car so i dont know much aboutr saturn but most cars when you pull the dimmer back all for com on so one told her it was the relay i dont think thats it

gas tank leaks, so i put up on blocks to drop tank. i took off exhaust/muffler pipe. but now i need to drain fuel to less than 1/4 capacity and also relieve fuel system pressure. how do i do that since i have no money? i attempted to siphon the fuel many times in various ways but i wasnt able to. i decided to go ahead anyway and remove the muffler and the pipe it was attached to but now i realize i need to drain the tank (which is little over half full) and relieve the pressure but i dont know how or which to do first. do i need to run the engine at all in the process? and if so,will i need to reconnect the exhaust?

my gas tank is leaking for my 2003 Saturn LW 300 and I can do it myself I have all the tools but I just need to know how and what to take out first. my car is already jacked up and sitting on blocks

I noticed a gas smell coming from under right side rear passenger seat, mostly from outside only. couldnt find a puddle underneath but when i took a closer look i noticed the whole underside of what im pretty sure is the gas tank was wet with a single drop (of gas, i assume) was pooling and ready to fall. I have every tool imaginable for home AND auto repair left to me by my grandfather, but very little knowledge of how to fix it myself. Can/should i do it myself? I also have very little money. If i have to replace the tank, then i will. but i just want to know if there is a simple, cheaper solution (assuming the tank itself is not cracked), such as a replacement gasket, or tightening that needs to be done somewhere under the car. Thanks! There is no check engine light or error code anywhere fyi.

Engine light went on a few months ago to check coolant. Added some. Month later, light on, added more. Week later, added more. Now every other day adding coolant. NO puddles underneath car, but drips of coolant on passenger side of lower engine. What may need replacing/repair? Thanks.

does this car come with a factory amp???????

I have heard a lot of "dialouge" about 4wheel alignment. I recently had a pair of new tires installed on the rear of my car, and was told I should have a 4-wheel alignment. I was quoted a price of $75 + parts and was told it would take about 90 minutes. I waited for over 4 hours! And, the total cost was over $244 which included just $58 for parts, but an additional $90 in labor!!! ($21=tax+fees)

I don't undersyand why I can't find out what the this problem is. Please help
