I have a bad map sensor on a 1996 olds 98 and i cant find where it is

FIND A SHOP PROTO, ONE CAN FIX CARS FAR AFIELD

MAP SENSOR DIED
GEE CAR OLD, NEVER SEEN ONE ME THIS OLD WITH OUT 10 PROBLEMS.
IVE RESTORED MAY 96 CARS, i LIKE THEM. AND SOLD THEM.
BEST IT GET IT SCANNED , IF A SENSOR IS DEAD, IT SURE WILL TELL YOU IT IS. LIKE A DEAD MAP SENSOR
AND NO VACUUM LEAKS CAUSE FULL SUPER FAST RPM IDLE AND HUGE POWER NOT LESS NOR LEAN NO RICH EVER.!
ON MAP BASED ENGINES, JUST LIKE MY JEEP 3.8L
BUT YES BAD MAP WILL CAUSE SUPER LINE OR RICH YES.
THAT IS BECAUSE I LIES TO THE PCM AND THE pCM MIXES UP FUEL DEAD WRONG

1. P0107: MAP Sensor Voltage Too Low (OBD II -1996).
2. P0108: MAP Sensor Voltage Too High (OBD II -1996).

MAKE SURE MAP IS NO FALLING OFF OR LOOSE IN ANY WHERE. INTACT VISSALLY

MSFIRE CODES:
OR p03XX CODES.
SCAN IT, AND NOT FORGET TO SCAN IT.
CHECK FUSES.

SPITS WHERE? BACK FIRES WHERE?
TO AIR CLEAN OR TAIL PIPE END TO AIR CLEANER ,WOLD BE BURNED INTAKE VALVES
IF VACUUM TEST SHOW IT STEADY IS GOOD BUT BOUNCING IS SUPER BAD.
OR SPITING
IS THE DISTRIBUTOR BOTTOM CLAMP LOOSE, YES BINGO , NOW TIMED CRAZY WRONG. AND WILL BACK FIRE IF ADVANCED WRONG.
THAT IS ALL i CAN THINK OF , FOR ANY 1996, MAP BASED EFI ENGINE.
TO BAD i CANT HEAR IT SPIT. SEEN VAST SO IT. ME ,FOR 50 YEARS

You check a map sensor using a hand held vacuum pump and a voltmeter

My bet is on a bad Oxygen sensor for the random misfire. Don't forget there are upstream and downstream Oxygen sensors. Check the Rock Auto site for prices. It looks like you can replace both for about $60.

Replace MAP sensor.

Hi at the end of your air cleaner tube is a square box with 4 screws and a plug in it. This is your map sensor

Several things that cause poor gas milege! Bad thermostat,temperature sensor,MAP SENSER,OXYGEN SENSOR ,MASS FLOW AIR SENSOR,PLUGGED CONVERTER,FAULTY COMPUTER,CHECK IGNITION TIMING.
lOW TIRE PRESSURES. VACUM LEAKS,TO MAP SENSOR FUEL PRESSURE REGULATOR ,AND INTAKE MANIFOLD,PLUGS MISS FIREING BAD WIRES,DIRTY, WORN OUT SPARK PLUGS .

follow the vaccume hoses to the passengers side shock tower area,the map sensor will be the one with bot wires and hoses going into it.

22 is a map/baro sensor code. They have a high failure rate often seen by GOOP or silicon in the vacuum hose near the sensor (it leaked out of the sensor when the sensor innards failed). 98 is a fuel pump circuit code. I would tend to think your main problem is the map, they can get very iffy and intermittant when they go bad. as usual, have an expert diagnose both codes properly.

check the iac valve. the sensor on the back of the trottle body. make sure the plunger is functioning properly. a haynes manual will tell you how to check it. if it s not functioning right it s only about $40. i had a similar problem with a 98 5.2
