SOURCE: checking the fault codes

Yes.  Next to the ash tray there is a black slide off plate that reveals the OBD I plug.  {1996 and newer can be read with an OBD II reader (read for free at Advance auto or Auto Zone)}  Once you reveal this plug on the 1995, you can plug in a single jumper wire (or even a paper clip) in the #4 and #15 pin hole.  There are two rows of pin holes, count from the upper right to the #4, then on to #15 (which will be the second to last pin hole).  Turn the ignition switch on (motor not running), insert the jumper wire for about 3 to 5 seconds, then remove the wire.  The ENGINE LIGHT will flash a hold, then the code, which will go something like this, flash, flash, PAUSE, flash, flash, PAUSE, flash, PAUSE, flash, flash, flash, flash.  Then it will repeat the codes if you just sit there and observe it.  The code in my example would be a 2214 code.
Below are some code I found on a website.  I hope this helps.  Now I ask that you take the time to answer someone elses question.  Lets all share.  Good luck, "Peace through power and knowledge"

SOURCE: CHECK ENGINE LIGHT: '95 VW JETTA

That only works on old OBD 1 computers - unhook your battery for a couple hours - that might put your computer back to default and you can take it to auto zone and have them scan your computer for free.

SOURCE: 99 jetta 2.0 check engine light. HELP

Replacing brakes will not shut the abs light off. You have either a bad sensor or accumulated dirt on a sensor. There's a sensor for each wheel so you have to either pull a code or visually see which sensor is bad, craced, chiped, etc, then change. As for the CE light, go to auto zone and they'll hook it up and tell you why it's on. You have to use a scanner to find out.

Acceleration problems


If I were going to guess, which is apparently what your mechanic is doing, I would say the problem is in the ignition coil. Ignition coils work ok at low rpm but as the rpms increase the coil will short out and cause the car to miss.

Why does the engine shake when slowing down?


The engine will shake when slowing down, because releasing the accelerator drops the rpm of the engine immediately. The engine only "knows" it has slowed down and will shake the same way if standing still.

There are many reasons for the shaking. All are due to needing a tune up. Poor timing, plugs, wires, cap, rotor, etc.

If you need help fixing something, give me a call.

p1545 is a throttle control malfuction code

You can try to reset the throttle body by opening the hood and drivers door then turning your key to the accessory position. You will hear the throttle body whir and click. It may take up to two minutes. Afterward, the car will relearn your habit of driving and adjust accordingly.

1996 VW Jetta with 2.0 engine. Dies when slowing from high RPM


Check your vacuum lines, make sure there is no leaks, and go from there, then all you electrical connection in the engine compartment.
I have a 1996 Jetta Trek Edition, the hoses, and wire harness, are so brittle, any movement can cause hoses and wire insulation to crack.

Engine stopping at when slowing down


check and make sure that there is no vacum leaks, such as any broken hoses especially the duct hose from the throttle to the mass air flow sensor , other tha that you have a defective idle control valve
