Warning(?)/Observation about Hüco Ignition Units
They don't play together, well!
(I broke my factory ignition amps) by trying to remove them. I was happy to find the Hücos (made in Germany), at a cheaper price. After installing them, however, my idle would sporatically drop, and stumble when putting into gear.
I thought it might be the reference sensor, and ordered one, but being impatient, I bought some Bosch (made in USA) units, today.
Here's what I observed: (2) Hücos = stumble, (1) of either Hüco + (1) Bosch = purring, (2) Bosch = purrring.
I reckon there must be a ciruitry thing that makes two Hücos interfere with each other.
Hüco (Hueco)# 13 8012
BTW, look around - you should be able to get Bosch units for ~$60/ea.
Trivia: the Hücos have an aluminum base, the Bosch, steel.

I suppose, but since both Huco units worked when combined with a Bosch, I doubt it.

It appears the problem was non-resistor Bosch plugs - W7DC, versus the factory WR7DC. The Hucos can't handle the RF.
(I put in some colder plugs with resistors.) WR6DC+, to go along with more cam and ignition advance. I reinstalled the Hucos, and the stumble did not return.
I've got proper spares, now, I guess.
