Hello Sam,
Sounds as though you have really run the gamut on that. One thing i did not
see was the oxygen sensor... I would have started w/ that rather early on.
Also, if I'm not mistaken this is still a CIS car so you should be warned,
the EZL for your car is on a 2-3 year back order already.. I know of no
less then 5 M104 CIS cars that are DOA as they can not get EZL's for them
anymore..not from the dealer, the breakers and they are Not rebuildable.
Try the O2 sensor and let me know how you make out.
