Gotcha.As for the transmission, yes it's a 4L60E.
It isn't slipping and I'm certain it's an engine related issue. I don't believe my trans would cause back firing through the TBI out of gear.
I greatly appreciate it, I've been battling this for over 2 years so anything helps at this point.Gotcha.
You've done good work and received good advice from folks much smarter than I- I'm just trying to think outside the box.
I've seen electronically controlled trannies do really weird things...and not slip.
No but, you need to disconnect the battery to reset the EST fault you get from disconnecting the BLK/TAN wire.Does the battery need disconnected (to reset computer) after messing with the initial timing to reset timing curve? Or is that not a thing?
