So I'm a bit confused.... is the ICM and the ETM the same thing?

Nope...as far as i can see...you're talking about ECU(s).Engine & transmission(if it's auto).
They are at the location you discribed.
ETM is Electronic throttle module and it should be downstream of air filter plastic ribbed pipe where it connects to engine(as far as i remember)...but it's definitely on the air filter line on the engine.

The OP has a turbo C70 so the ETM will be located on the end of the long plastic intercooler hose under the intake manifold.

On turbos the air cleaner goes directly to turbo inlet via MAF.

Hulk, your ETM is a throttle module, it's the fly-by-wire equivalent of a throttle body. Instead of a cable, your throttle is opened electronically. Last stop for air into the intake manifold. ECUs are in the box with the cooling tube.

What happens when the car is dieing?

Ok I'll try changing out the ETM when I have time this weekend and keep everyone posted on development because if it doesn't work it's back to the drawing board for me.

If you swap out one from an auto chances are it won't work. You need one from the same engine AND transmission.

That's going to be very hard to find... There is not that many manual trans 99 c70 of that year... any suggestions? I have a pretty rare car to my knowledge

You just need another good used ETM, a Dice (you don't need Vida at all) and then you contact MVS member doublebug; he will do the rest.

Would it need to be C70? shouldn't any 1999, 70 series manual trans/HPT ETM work? (or LPT, I forgot which you have)
