I have a 1990 Loyale, non-turbo. The CEL has come on, giving the codes
34 EGR Solenoid or Circuit
35 Purge Control Solenoid or Circuit
I have replaced both of these solenoids, and the EGR valve, and the CEL stays on. I have reset the CEL, both with the connectors under the hood, and by disconnecting the battery. The CEL goes out, and comes back on a few minutes later. The problem started out with just code 34, but now comes up with both codes. I have checked all of the lines, and everything seems connected and in good condition. I'm wondering if there is any other part of the engine that will trigger these codes. I am past due getting it smogged and registered, and would appreciate any help figuring out the problem.
Thanks
