'98 Jimmy loosing rpms and sputtering
THIS THREAD has the book method for timing these EDI ignition systems. I figured I would throw it in here as I found it in my musings a bit ago.

As things stand, obd2 and parts arrive Monday. Montana weather and work permitting, I hope to have an update for you near then.
Thank you both. I've been using this video as a guide for changing the distributor. It goes into everything in the post from swartlkk, except #3, the alignment of the distributor post.

“I can see there's someone in the audience who doesn't believe you can affect the ignition timing by moving the distributor --- now I gotta find out where he lives so we can pick a convenient parking lot to discuss this ..... <ahem!>”
Dude, this ain’t fight club, it’s a forum of experienced mentors helping a community of diy’ers to fix their trucks and become better mechanics. I can assure you that threatening violence will not improve on your ignorance about Blazers and as Swartlkk said, it’s against the forum rules. Some of the best Blazers technicians on the planet hang out here. Stop threatening people, listen and learn.

I hope it wasn't the device on Amazon that I suggested in post #9. Please let me know if it was.

Here is another that is cheaper and actually says it need a third party app. Wish I had seen it before.
APP COMPATIBILITY – Compatible with popular Android apps like Car Scanner ELM OBD2, Torque, OBD Fusion, Dr. Prius, CVTz50; NOT compatible with BimmerCode, BimmerLink, ABRP, and other Apps that require specialized hardware. Note they even say compatible with Torque. If compatible with Torque, it is compatible with Car Gauge Pro.
