I really don't think you would have a fuse problem . You should hope not anyway , fuse's don't go bad or blow for no reason . A blown fuse would be caused by a direct short to ground on a battery power supply circuit , high current draw . I would look at the flasher or switch as probable cause . Viewing a wiring diagram an testing the electrical circuits is the best way to find the problem . Turn Lamps
With the ignition switch in the RUN position, battery positive voltage (B+) is supplied from the IP fuse block T/SIG/BU LP/BTSI fuse 1B via CKT 539 (PNK) through the turn signal flasher to the normally closed switch in the turn/hazard switch via CKT 16 (PPL). With the turn switch in the left turn position, battery positive voltage (B+) is applied through the turn switch and two paths to the turn lamps. One path is to the left front park/turn lamps and the side marker lamps via CKT 14 (LT BLU). The second path is supplied to the left tail/stop/turn lamps via CKT 18 (YEL). The lamps go on immediately. The lights begin to flash when the current heats up the timing element in the flasher, and the flasher repeatedly opens and closes the circuit. A similar procedure is followed when the turn switch is in the right turn position. Battery positive voltage (B+) is supplied to the right front park/turn lamps and the side marker lamps via CKT 15 (DK BLU). Battery positive voltage (B+) is supplied to the right tail/stop/turn lamps via CKT 19 (DK GRN).

had same problem i would check the Idel Air Valve and also check all of your vaccum hose lines makeing sure there are no cracks or splits in rubber connectors if there is repair immediatelt because over time they start to dammage the internal parts fo the engine and if youve replace tps mass air etc. sounds like a vaccum hose problem

You must take it to a dealership and they will unlock it for you. There is a specific dealer code that will unlock any radio and once they do it, you pick one that you will remember. This is part of the anti theft. Hope this helps.

REPLACEMENT
The hazard flasher is located forward of the console on all N-Body vehicles. The turn signal flasher is located behind the instrument panel, on the left side of the steering column bracket. Replace the flasher by unplugging the old one and plugging in the new one. Confirm proper flasher operation.
The flasher is located behind the dash (trim removed for clarity)
PLEASE DON'T FORGET TO RATE!

Unfasten the starter motor electrical connections. You may want to tag them first to avoid confusion
Exploded view of the starter motor electrical connections
The starter is attached to the engine with 2 mounting bolts (see arrows)
Unfasten the front mounting bolt (1) and remove any necessary shims (2), noting their locations for installation
Unfasten the long starter mounting bolt, then remove the starter motor from the vehicle
Before installing the starter motor, make sure the electrical terminals are secure by tightening the nuts next to the cap on the solenoid battery terminal and on the "S" terminal. If these terminals are not tight in the solenoid cap, the cap may be damaged during installation of the electrical connections and cause premature starter failure.

To install:
Note the location of any shims so they may be replaced in the same positions upon installation.

your gauges need to be replaced it sounds like you have a bad mother board on it.
