What scanner Do I need to buy?

Also yes I did change plugs, wires, O2 (delco), Air Filter, TPS, MAF at this point.

Also checked hot and cold resitance on the coils and they are matched PERFECTLY at 6.43/6.42


SES Light is On as is the traction light. the *Both ride lights are on* touring and normal....

There is no scanner in town I can even buy that reads either of the cars. Dealer is the only way.

I will clean the EGR when I get off work and see where that gets me.

I assume rubbing alcohol or Throttle Body Cleaner for that?

2 I can think of right off the top of my head.... Actron CP9110 with the 9111 card I think or Actron CP9145

Both of thesae will read the 94-95 GM H and C body hybrids

Carb cleaner or TB cleaner. Either will work. And a brush. The 94+ linear EGR isn't as responsive to cleaning as the 91-93 Digital valve, but it might help.

Don't forget a new gasket. You might need it.

Is the EGR Swapable on L27 vs L67 (both 94) I assume yes.


I get off work in 20 minutes, picking up gaskets and a new wire brush

Yes in 94 both of those cars used a linear EGR and they should be swapable
