Having high idle issues and will stall out of nowhere. Changed both fuel pumps and fuel filter so far issues have gotten better but are still there. Check engine light will come on intermittently as well. Any help is much appreciated. Thanks

What are the codes it's throwing with the check engine light?

Not sure what motor you've got; mines a '95, but I'd suspect the Idle Air Controller. If it's not actuating properly it'll cause the fuel mixture to run rich, which would explain O2 feedback the CPU is getting and the high revs.
