My blazer has the timing chain tensioner issue. Fools the knock sensor into forcing the computer to retard timing. I was able to verify this with only a live data stream. You may want to consider this.

take a business card and cut out a washer to fit between the crank shaft sensor and timing cover to shim the sensor out a little and see if it helps, cured my problem.
