WHEN USING IT RANDOMLY IT SPEEDS UP - Stairmaster Nautilus SM916 Stepmill - Refurbished

No make or model of vehicle as sorry, cannot comment.
Don't use it until it is fixed, possibly a wiring error on the steering wheel.

Check all grounding connections, free of corrosion,tight and undamaged

Recorder fan hi! Check the voltage of your motor and then fit a generic motor to it. Check the belts and lubrication of the shafts of the capstan bush a small drop of sewing machine oil works wonders also check the roller geometry is it round and the tyre touching surface is it flat or is it bulged If bulged replace.

engine speed sensor problem take it to a dealer unfortunately..

It could be an internal problem with a pump, or it could be it needs to be serviced really bad. Most 'oil change' places can also do transmission services... I'd try that first, before paying a big repair bill to a shop. good luck.

sounds like a wheel bearing very common in these

RAM is a type of computer memory accessed randomly during hard drive processes.

A computer's RAM is considered "random" because any byte of memory can be accessed without processing previous bytes.

Purpose of RAM

RAM is used to load and run programs or applications on a computer's operating system. More RAM means more applications and programs can be run simultaneously.

SRAM

Static Random Access Memory, or SRAM, stores data on a computer in a static method, meaning the data stays the same with power being supplied to the memory chip. SRAM is the faster RAM when compared with DRAM.

DRAM

Dynamic Random Access Memory, or DRAM, is a type of memory used in personal home computers. This type of memory must have an electrical current to refresh. DRAM is used more commonly because it's less expensive to manufacturer and install in chips.

EDO RAM

Extended Data Output, or EDO, is a new type of DRAM chip that uses technology to add 10 to 15 percent more speed than normal. A computer that uses EDO technology must meet the chip requirements or the EDO will not be recognized.

FPM

Fast Page Mode, or FPM, is a RAM speed enhancement that uses rows of bits selected in columns and rows of the memory.

FPM is used in EDO RAM.

well, First I have to ask what is your ISP and what is your internet speed supposed to be? If it is in fact 1.5 Mbps then you may need to upgrade your internet speed to say 5-10 Mbps.

Also, What applications are you running? Such as Internet Explorer or Firefox? Internet explorer can be nuisance. Things such as Anti Virus Software can hose up your internet speed if you have only 1.5Mbps as well. Hope this helps. If you have other questions don't hesitate.

Your ISC (Idle speed control) needs to be replaced. This is located on the intake.

Try calibrating the console. If it doesn't work, you'll need a new motor control board.
