I thought that your car would not start sometimes. Now you're
fooling with the O2 and the CIS control unit, one thing at a time.

You replaced the coil. Now determine if you still have a no-start
sometimes.

Good luck

Loren,

The Mechanic I took it to in the first place told me the coil was bad and he replaced it with the same kind of coil along with a new distributor and wire harness after that it worked for a week or so.

My question is could have the coil gone bad again and how can I check it?

The only thing that I changed over the weekend was the O2 sensor because looking through the records it has not been done in a long time and in Wayne's book the sysmptoms seemed to be similar.

Thanks,

Rodney

It's not easy to check a coil for an intermittent operation.
Don't use the silver coils. Buy a cheap VW coil at Pep Boys
for about $10 for testing.

Good Luck

You *must* use the correct coil, or you risk burning out the CDI. A VW coil is not the one to use. OEM part # is 901 602 502 00

It won't hurt the CDI. If it does, I'll send you a rebuilt one N/C.
This is only for testing.
