Question Asked: I have a P0300 code for a random misfire.
September 09, 2011, 06:42 PM
I did a tune up and all was well. Shortly after I developed a random misfire. New plugs wires, fuel filter. It is a coil over system so its not there. The only thing I can find is the fuel pressure is low. Around 48 psi instead of 62 psi. I didnt get this filter on wrong thanks to the little arrow thats points that way ---->. I have wondered it the fuel trim adjusted so far out with the old plugs that it is just relearning but how long should that take? Could my fuel pump really just be putting this low pressure out all of a sudden? I have stumped myself.
Question Answered: oil in resivior why?
July 10, 2011, 11:57 PM
If oil is getting in your coolant, then coolant may be getting in your oil. Check your oil dipstick and oil fill cap. Does it have a brown milkshake substance on it? Does the oil seem to be a funny color or thin? These liquids are separated in your engine by gaskets such as your head or intake gasket. If they are going bad then it is possible for 1 or both fluids to contaminate another system.

Question Answered: new incident: most of the coolant had leaked out under the car.
July 10, 2011, 10:02 PM
Leaks can be tricky to find. A tool that may help find it is a cooling system pressure tester. Some leaks are only evident when the system is hot because the pressure is greater then. You might be able to rent the tester at your local parts store. After filling the system with water, you hook it up to the radiator or surge tank depending on the model. You may also have to crimp off an over flow hose. You will hear the pressure escaping usually. I use vise grips to do this. This is also a nice tool because the car can be cold making it easier to get in the engine bay to search for the leak.
Question Answered: after i start the motor a light on the instrument panel O/D off
July 10, 2011, 09:50 PM
O/D usually stands for Overdrive. Some cars have the option to turn the O/D off. Sounds like your car does. Check on the gear shifter for a switch. It may even say O/D on it. It could also be a button on the dash. If you find something you think might be it, flip it on and off while the car is on. Watch the light and see if it changes.
Question Answered: where is the electric motor for power steering system
July 10, 2011, 09:23 PM
There is not really an electric motor. I heard there was a a technical service bulletin or a recall on GM cars with that steering system with those symptoms. Basically all it may need is a reprogram which you will have to go to the dealer for so they can trouble shoot the problem. They will have to confirm that is the problem before they can do anything.
Question Answered: Got a radiator leak. Can this be fixed or the radiator must be replaced?
July 10, 2011, 09:16 PM
Depends on how bad the leak is. Does there appear to be a lot of corrosion around the edges of the radiator or near the leak area? Really it can go either way. Your best bet is to locate a radiator shop near you and take it in. They will be able to be more specific.
Question Answered: I cannot get left seat to go upright in 3rd row of Denali, -lever "1" is stuck.
July 10, 2011, 09:11 PM
I had a problem similar to this when i worked at a Gm dealer. The cable had wore out and broke. To remove it I had to disassemble almost the entire seat while still in the vehicle. I hope this is not the problem but I have a bad feeling about it. Trace the cable from the level to the other end. Then operate the lever to see if you are getting the proper action from the mechanism. If it seems there is good movement then maybe its just stuck. If there seems to be no movement then the cable is broken. I didnt not handle the bill side but I believe it was at least a few hundred dollars.
Question Answered: I am having water draing on the rear passenger floor. Need to know approx. cost
July 10, 2011, 08:21 PM
Are u sure if leaking in the back? The a/c system doesnt run back there so its 1 of 2 things. First something else is leaking. Second the drain for your havac system is blocked in your dash and running under your carpet from the dash to the back. Check to make sure the carpet in the front passenger area isnt wet. Could also be your heater core leaking. Is your coolant low, the inside of the car have a sweet smell, or the windows steam up? Really need to locate source to go any further.

Car Review: 1990 Mazda RX-7
July 10, 2011, 09:46 PM
This is a very unique vehicle. The rotory engine operates better at higher rpm than a conventional piston engine. Another highlight is the rear wheel drive that it has as rear wheel drive is getting harder and harder to find. Comfort was second to speed and looks in design. Also not the best car to transporting ppl or groceries. If you want a sports car, this is the car for you.
