I have a 92 Loyale and I think the ECU has a problem, no matter what code 34 will not go away:mad:! I was wondering does the EGR system affect my AFR? Since the code took up residents my MPG have cut down about 1/4. I replaced the solenoid but still get the code. Is there any way around it? I would like to install a HHO system but want to line out the system first. I have a Weber carb that would totally bypass all but from all my research I've found carb not good on EFI engine.

 

PHins UP!!! ~~^~~

No,not directly.It will affect MPGs in other ways,however.

Install a working solenoid/check wiring to cure your code.

Bad ECU doubtful but easily verified w/a test light.

Any code that kicks the CEL on will put the computer in open loop, so it will be running just a bit on the rich side.
