You don't need to even spell computer to understand the code.
The reader is a "plug" that you shove in the socket down by the drivers right knee (it won't go in wrong - it only shorts two of the pins together, you can do it yourself with an unbent paperclip), then you turn on the ignition (but don't start the engine)>
The "Check Engine" lamp in the center panel (called the Driver Information Panel DIP) will start flashing.
Just count the flashes. It flashes each code three times.
e.g. - a "12" is one flash, pause, two flashes ... longer pause -
then one flash, pause, two flashes ... longer pause -
then one flash, pause, two flashes ... really long pause.
then the next code sequence.
all the codes are two digit numbers
the first one is always a 12 (confirms system working)
I think the last one is always the same too, but I'm not sure.
after it shows all active codes, it will repeat the whole thing over.
the codes are usually reset by disconnecting the battery for 30 secs.
some codes can be reset when you start the engine
Look the codes up in the booklet.
Piece of cake. See -- no geek talk at all, you'd never know I'm a serious computer geek. My job is to show CEO's that computers can turn their business around, and you know how reluctant CEO's are to learn or change anything.
Be certain to use good quality premium, unleaded fuel.
Try to avoid ethanol, or unbranded fuel.
I'm having starting problems with my 89 now. I suspect a tank full of bad fuel. It's kinda bunkered up for the winter but my mechanic is gonna be checking out the resistance in the injectors soon. I'm getting some codes, but nothing to help so far. My "Check Engine" light isn't coming on in normal use.
