I had to replace 2 of my fuil injectors because theyvwere bad my brother has the same car and had spare ones. Now it's boging kinda someone said it could be obd1 injectors in it??
Its odd that you had to replace two fuel injectors. Its rare that one fails let alone two at once. Makes me think the fuel injector wasnt the initial problem to begin with. Regardless I would have replaced the full set so you are running a matched set. It has nothing to do with OBD0 vs 1 but its possible they could be dirty and need to be cleaned causing them to inject less fuel than the others.
