The car's gages go crazy back and forth. Oil, fuel, battery, and the rpms run high. I have replaced the oil pressure switch, egr valve, throttle position sensor, intake control valve, coils, spark plugs and wires. Any help would be appreciated.

HAVE YOUR BATTERY TESTED FULLY AT A POPULAR AUTO PARTS STORE

OTHER THAN THAT YOU MIGHT TRY TAKING YOUR NEG BATTERY CABLE LOOSE FOR A FEW MINUTES THEN RECONNECTING IT....THIS MIGHT RESET MR. COMPUTER, HE MAY HAVE RECOGNISED LOW VOLTAGE AT SOME POINT........HAVE YOU HAD TO JUMP START HIM IN THE RECENT PAST?

CHECK CONNECTIONS TOO...SEE MY LINK
