3.2 missing badly - out of town.....help requested

[198491132]

New SW Chip installed 250 miles ago. As I was just leaving Watkins Glenn a huge misfire started above 1500 rpms. Was able to get to my destination but can not move on until this is fixed. Called Steve W, he suggests a bad/cold solder joint on the jumper I added on the DME board, to allow for his chip to go to 4K Memory.

Why would the car run great for 4 hours, if this was the cause.

Do not have equipment to re-solder, but will get some later today.

I changed the DME relay, no good. Checked all the plug wires, injectore feeds, saw nothing that fell off.

Would a messurement of 461 ohms across pins 1 and 2 on the DG speed sensor be an issue? It is out of tolerence according to the manual...(960 +-). I did have to replace the ref sensor about 1500 miles ago. I could not remove the speed sensor, so it remained.

Would the car react the way it is if this is the problem? Terrible miss fire, back fire and wanting to shut down after 1500 rpms.....

I did replace the DME relay....and DO have a speed sensor in the car, issue there is I have to get it to a shop, as I tried for days yo get it out myself last Summer.

Stranded , out of town.....
