So I’ve had the issue of bucking and limp mode while hot for a while. Replaced a multitude of things to no avail.
Ignition coil and ICM- same problem
Spark plugs and wires - same problem
Checked all grounds- same
Fuel filter- same
Emptied E85 and filled with new E85
Took off fuel rail and blew ecu fuse, new fuse- same
Changed timing on distributor to roughly where it was but not sure if it’s completely correct.

My issue is the fluctuation of the ignition timing on Hondata. At idle when cold the AFR sits at a nice 14.7-15 but when warm it’s abolition 11 and sounds like it’s gonna stall. Is this a problem with the distributor base timing or could it be something else causing this? By no means an expert on timing

If the TPS calibration was off wouldn't it sense this in Hondata? It shows my tps as being 0% at idle but the ignition jumps between 19-26 degrees and my injector pulse also fluctuates.
