[s-cars] Stumbling saga, update......

[Jim Fleischer]

Hey guys,

OK, so I put in fresh NGK BKR7EIX plugs this morning, and things greatly improved, however still not right.  Whereas the car is definitely much more driveable now, it still cuts out at high boost.  No more stumble at lower revs under load, and the stumbles are fewer and shorter, but still there at high boost particularly between 3K-4K RPM in third and fourth gear (haven't had the road to get it in fifth under boost yet.)

Unplugged the injectors again and the car is just not driveable with any of the injectors unplugged.  The miss is quite apparent, and different from what I normally experience.

Also tried unplugging the MAF sensor, and the car is jerky and undriveable until the revs come up, even then "limping" for sure.

I did not replace the spark plug boots, as I wanted to see if the plugs made the difference.  Is this the next step?

I now defer to the list and it's infinite wisdom........

Thanks!
