Ok I know I read a while back about a surging issue some guys were having. Time for me to jump in on this. I never had a problem with a surge until yesterday.
Background:
Over the weekend I changed my plugs and I went with the same OEM champion coppers that were already in it. I gapped them at .40 and put them in with no problems. The old plugs that came out were a light brown in color with no oil on them, and the tips were not rounded at all and the gaping on all the old plugs was at .40 as well.
Current:
Yesterday I wasn't paying too much attention to the surge since it wasn't too noticeable and I was off in la-la land. But today it was much more pronounced and when I threw it in park to get out of the truck it surged once then died. (first time the truck has ever died). Fired it back up and got back to the office, put it in park and watched it. The rpms were surging from 400-1000 and took about 60-90 seconds to level back out at 650rpms.
Now I know from reading about a SC fix that eliminates the surging and puts the idle around 750rpms if I remember right. But my question is if I didn't have the surge at all before changing my plugs then why would it show up out of the blue after the plug change if the gaping on the new plugs was the same as the old ones?
And I haven't updated my SC for while now and I would like to figure this out without doing the update since it wasn't surging with the old plugs. I want to make sure this isn't being caused by something else first.
Thanks.
