SOURCE: Need to adjust the timing for convertible top 1999 BMWi

It is (normally) not adjustable. If a mechanic told you the car is out of time, check with another mechanic.
If you have a damaged reluctor wheel, the crank position sensor can get mis-readings and cause the car to fire out of time. I recently saw a Lexus that had its reluctor wheel damaged during a timing belt replacement. I have heard of similar mis-haps on BMWs. A related problem is damaged shielding on the crank position sensor lead. Such damage alows electrical interference to get in to the ignition trigger signal from the sensor, and can cause mis-fires.
If you put in an aftermarket performance "Chip" in your ignition computer, it will change the timing program. Such chips are illegal in most states and may be detected in an emissions inspection. Is that what happened to you?

2008 chrysler seabring convertible top is stuck

The top is operated by a electrically driven hydraulic pump, so more then likely you have a loss of fluid due to a leaking hose or cylinder and this lowers the system pressure and causes the top to stop functioning.

How do you adjust the carb on a 2.4 engine, 94 nissan pickup

You should have an air mixture and an idlig screw. The air mixture screw is set first untill engine idles evenly. then the idling screw is set untill the idling is as slow, being even, as possible. 800 to 850 RPM should do the trick. Then go back to air screw and FINELY adjust. Try to keep air filter onand make sure it is clean, new and not leaking air.

Convertible top switch works sometimes but other times it does not work

If the convertible top switch not working properly every-time.Then the switch and its electrical connections/wirings needs to be checked. The switch is typically located in the trunk, positioned right beside the covering of the left or right tail light. The switch should be set to automatic, not manual. If the switch is properly set, then other things are causing the problem. The other things blocking the top to move up and down is its hinges.If the hinges are bent or cracked or got loose then this can be the other reason. If the hinges are in good condition, then check the convertible top struts. These are the mechanisms that lift the convertible top. Lift struts deteriorate due to wear and tear and will need to be replaced if it's the source of the problem. Another very common reason for a not working convertible top is the worn out elastic straps. Furthermore, the convertible top's fuse could be blown out and as a result it's causing the convertible top to stop working. In newer latest models the convertible top is controlled by a single button conveniently located next to the handbrake. You press a button to release a center locking device - none of this moving the sun visors out of the way and releasing two latches on other sides of the car stuff! - then twist the device with its conveniently large handle. Then you press the button, and if you're lucky, it'll work the first time. If not, try it again! The temperature display goes from blue to yellow and shows a "convertible top opening" graphic, and the top opens up and neatly folds itself in back. You can release the button when it beeps again. Putting it back on again is the same basic process, though you have to wait for the beep, then press the latch release, twist it, pull down, then re-twist the latch again. Thanks. you can rate this solution and show your appreciation.

Convertible top

make sure your car is in park and that you have your foot on the break....if you release your foot it will stop. So keep your foot on until it is fully open or fully closed and the passenger seat has returned to where you had it set prior to opening or closing
