Top 20 1997 Pontiac Bonneville - Page 3 Questions & Answers

there is a slider switch just under the headlight switch that controls this

maybe a map sensor, the large sensor inline with the air tube just aft of the airbox. it could also be a MAP sensor or manifold air pressure sensor. both are respnsible for correlating with the engine computer to control fuel.

Check the fuse boxes, it's normally labeled. If the label has come off or is unreadable, check them all with a fuse light. These can be purchased cheaply and are very easy to use.

COULD BE FUEL PUMP,SPARK PLUGS

when the engine light flash is a misfire very bad code P0300

check that you have the firing order right as you may be 180 degrees out. with the plug leads

Replace the brake caliper.

Clean throttle body very good.Check air flter,

If you have checked fuel pressure with a gauge and the pressure is normal, are you getting spark to the plugs ?

The warning light is on because the computer does not accept the chip signal in your key.The causes can be a bad chip, sensor in the lock cylinder, or a faulty module.You could try a spare key, otherwise you may need to diagnose the system.

You have a warped head now that leaks coolant into a cylinder. Take both heads off and have a machine shop grind them flat. New head gaskets and you're good to go. That's an over simplified explanation. hats a big job dismantling the engine. Replace the thermostat and flush the radiator too.

push the lock cylinder so clamp will mesh with groove. slide it from right to left

1997 Pontiac firing order is 165432

You have correctly trouble shot a plugged heater core. Install a back flush kit on the car. They can be had at an auto parts store. Get new anti freeze too.

Are all of the pulleys in a straight line with each other ?Is the spring on the belt tensioner tight ?

Hi there:Check this diagram on 1997 Pontiac Bonneville 3.8 liter V-6Hope this helps.

What have you checked so far ?Blower fuse ? Relay ? Resistor ?

Look for cracked and gummy vacuum hoses on the manifold. You may find one disconnected. Sometimes you can get by with shortening the hose slightly and then connect it back..

You'll need:-Thermostat-Thermostat seal (A rubber o-ring that goes around the t-stat. You shouldn't need an actual gasket, though there are gaskets you can get.)-10mm socket, also an extension will probably help-You will likely need a bit of coolant or water to top off the system when you are done.-First you can either drain a little bit of the coolant, or you can loosen the bolts and let whatever comes out comes out, it won't be much.-There are two 10mm bolts on the sides of the thermostat housing, remove those and move the housing out of the way. (To avoid losing any more coolant it'd be helpful to note to keep the housing end higher than the top of the radiator.)-The thermostat will be directly under the housing and you can simply pull it out and replace it with the new one.-There's no specific orientation for the thermostat besides top/bottom. Just make sure you put the new one in the same way, which would be with the spring side down.-Put the thermostat housing back on and replace the bolts and tighten.-Now you'll want to top off the coolant and run the car.-To help air out the system open open the bleeder valve on top of the housing (It will either need a flathead screw driver or a 7mm IIRC) and with the car running and up to temperature, open the bleeder valve and let the air bubbles out. Wait until there is a steady flow of coolant coming out then shut it and you should be good to go.

P0108 code definition is MAP (manifold absolute pressure )circuit high input, In other word its disconnected or it is connected and is internally disconnected, This code is not the VAF,
