well as some of u know by looking at my past posts. ive been having lots of backfiring and cutout problems while my car revs up under load. ive tried everything from ignition to fuel to ecu reflashes, etc...
well me and my shop foreman attached a timing light to the coil wire while we went to lunch. we noticed while the engine backfired, the light would flash real slow indicating a loss in spark. well got back to work and another master tech joined us while we were brainstorming. my shop foreman blurted out "try a jumper wire from the dist to the ground on the block (his '52 suburban needed it or it ran like poo). well i did just that on the way home. i made about 4 redline hits without it backfiring on the way home. it ran like i pulled a potato out the tailpipe. **crosses fingers to let it stay that way**
so my question is: how is the distributor grounded? thru the block? dist hold down? has there been issues before about this? i did a search for it and found nothing relevant
thanks all that have tried to help me!!! this site has the best ppl on earth!!
