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

[djdawson2 at aol.com]

 I would vote for doing the boots next.  Everything else you test is pure speculation until you can be certain that the path from the coil to the combustion chamber is in good shape.  $35 well spent... BTDT.

BTW, visual inspection of those boots won't tell you anything meaningful.  They can look just fine and still be shot.

Keep us posted...

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!
