Had wrong speedo in car-changed and reprogrammed computer-now 1189 comes up and can't find out why-replaced oil press switch-before speedo and computer change-it had misfire codes-could it have something to do with radio module? Should I take to another shop or replace computers? 1189 oil senser I believe. Need to get lite off to smog.

I think there was a software glitch on this code.
Did you have the software upgraded with the latest and greatest?
All of this stuff was done at a shop trying to resolve this code?

Okay so there is a communication error. If you like the car this is repairable. The modules need to communicate with each other.
