I can post the part # tomorrow night, should have it by then. So far, after the plug change, it hasn't missed a beat, but will change the CPS anyway, now that I have one coming. If the problem comes back following the install, I will post again. Again, I have a few misconceptions about this shop I am forced to deal with, since if he (shop manager) knows his stuff, why hasn't he heard much of this issue? Or was he a Lada salesman before this job? It's nice to find more realistic input from a good forum such as this!
