Ok, got new plugs installed, while installing plugs I ohmed out the wires also. They all looked good except when I got to #5 plug wire, was reading an open. Upon investigation I could get a reading while touching the wire going to the clip but not the clip it's self. So may have had an issue with it arching to the coil. Got a set of new plug wires and installed. The old plugs looked like they were running hot to me, very dark brown coloration but I've never inspected plugs from a SC car before so maybe thats normal. Almost like a rust color brown on elctrode and tips, not actually rusty tho...
Test drove car and still doing the same thing, it ONLY does it when the car is adding boost, when I say adding boost I mean when I can see the boost indicator on dash start to light up. The car changes sounds and starts to run rough. If you keep it in the boost then the SES light starts to flash indicating a misfire. The car runs great until it tries to boost. I sprayed all vacumn lines with carb cleaner while idling to check for leaks and all looks good. If I floor the car the boost indicator will show 100% like it should.
Thinking maybe I should get an HEI ignition tester and check each plug wire and coil pack to make sure it is getting proper spark under load.
Thoughts?..........
