It runs rough at idle and at higher rpms. You all can blame the wiring my guy did all you want, but if that's the case than how come my other CSVT didn't have the same problem?
My alarm guy knows wtf he's doing. So I'm pretty damn sure that ain't the problem.
And the stereo isn't the problem, that thing is run off it's own battery. As far as the turbo timer goes, it's very unlikely that's the culpret. Right now, it's looks to me as if it's the AFC that has the car f-ed up.

Sounds like the wires under the dash or attached to the PCM were damaged when this piss poor work was done.

The MAF reading on the S-AFC is just the voltage signal from the MAF. It's passed through the S-AFC so if the S-AFC is not getting it neither is the PCM.

You really don't want to believe it is this extra stuff that was added but more and more it's pointing directly at that!!!

Just because you took it to a "shop" doesn't mean it was installed correctly!!!
For instance I can bet you money they have NEVER installed a turbo timer on a contour before.


Also if they pulled a tach signal off he PCM it does not leave enough signal or the PCM to read.

There are just so many things they could have screwed up and the fact the job was done in such a piss poor way would indicated they are clueless (to put it nicely!)


Stereo is run off it's own battery??? It still has to be tied into the car's electrical system. What about grounding loops. Electronics hate grounding loops and your installer probably doesn't have a clue about them.


I still blame the installer at this point.

The S-AFC has built in protection but again a large spike or short can damage the unit and with what's been stated who knows what the installer hacked up.
