1992 Z28 "no communication" to ecm
I recently put a 357 into my z28. it had a 350 with H/C/I before and this current setup isnt much different except for bigger heads and a cam with more duration. however the car runs and drives but is very choppy and likes to shut off at idle. it has the SES light on. i put the OBD scan tool on it and it reads "no communication to ecm". i cant seem to fig out what the issue is. any feedback would be appreciated.
maybe i have a bad ground?
do i have to get a new chip burnt for this current setup?

No communication sounds like to me it's either cooked or at bare minimum not getting power. Sounds like it's running in limp home mode.
