So yea.... I an newer to these buicks and mine has done this before but it went away and I am not sure as to the cause of either, coming or going. However here is the problem, when you get on the engine and it hits 3000 rpm and the turbo starts to spool the engine starts to break up. I checked all the plugs, they look great. It is also kicking lots of fuel out of the tail pipes. Not sure the problem but any help would be great. Thanks
 
Could be a coilpack/module problem. The richness of your A/F mixture is probably because of not being burned (obviously :o). Gap the plugs at .030-.032 first and see if that helps, if not the Ohm the coil pack, if they check out good the module probably chit the bed.
 
So how do I check these out? What should they read? Ohm meter? Volt meter? And is the ign mod under the coil pack? Thanks guys.
