92 Olds Achieva, Speedometer & Tachometer indictors spike

\015 They spike at the same time and then settle back to normal operation. Check engine light goes on and off intermittenly. Check engine light does go off at low rpms but comes back on at highway speed or sometimes with just a little acceleration. Can't seem to duplicate codition as it appears random. There are no codes.\015 Posted / edited by AnonymousUser on : 08-08-2022
