spent the afternoon going through the exploded diagrams of VW parts on the VW computer... turns out (unless I missed something) that all the VW and Audi manual winder mechanisms opperate as a cable se ...

About an hour ago, I decided that my emissions off idle were too high.. its nice for them to richen up a bit off idle, but this was crazy, about 9% CO at 3500 rpm off load.

So I called a local guy ...

Hmmmm.. very interesting...

Mine looks like the picture here...

No paperwork came with it at all... just the dial, lots of pipes (which I have learned at for different connections..) but it seems the T-piece will only screw directly onto the bottom of the gauge.

When I say that we could not see anything going on with the trace/waveform, of course neither of us have any idea what we should be seeing in any detail... but we didnt see anything suddenly going str ...

Well, there is more confusing aspects now.

I used a multimeter for testing the dwell, a automotive one that has dwell and other car testing settings... it gave me the results I just posted.

But ...

Just been running some more tests as shown in the workshop manual, and as the sensor coil in the distibutor tests as within range (resistance), as the dwell is way down on spec, it mentions changing t ...

Hmmm...

Dwell as measured at the ignition coil, with a multimeter, I am getting the following readings..

1500 RPM - 27.7 degrees of dwel

5500 RPM - 17 degrees of dwel

The interesting thi ...

OK.... here goes...

Testing the mechanical advance and the vacuum advance.

I have found that the distributor is advancing the ignition (beyond the timing I set of 8 degrees) by the following amo ...

One olther thing Smoothie, It pulls away just fine, if anything it has a bit more low end grunt than other 924s I test drove when looking to buy one.

In fact it seems to run just fine except for th ...

Hi Smoothie, thanks for the post...

I will check a bit later (in the morning here in the UK), but from memory it seems almost like you can pull the distributor rotor arm straight up by about betwee ...

OK... So I just dug "the big red books" out of the loft (the factory workshop manuals that came with the car)..

Thought I would test the coil resistance... its 0.7 ohms between the two screw on con ...

Thanks for the FAQ CMXXXI, interesting reading.

Paul, The relay has a rev limiter built into it???

One question for everyone.... with the distributor cap off, if I turn the rotor arm by hand clo ...

Oh... I forgot to say..

Paul, have you seen a faulty relay acting like this before?

Paul,

Thats for that, I will try it out.

Which pins do I need to jumper together? is it like the 944 DME relay where you jumper the 3 big pins together?

I will try it tonight if I can figure ...
