1994 Pontiac Grand AM suddenly idles high, accerates very high in drive etc..?
The most common cause for a high idle in the 94' 3.1L is a bad TPS (throttle position sensor) ADDED: @ KARA, If you keep having to bleed the system continuously this indicates leakage from the combustion chamber via head gasket(s) in an unrelated issue! ADDED: This is a 1994, (OBDI) So unless it is a "hard fault" (TPS) signal shorted it will not set a DTC, The PCM will idle the engine at a normal speed when the TPS voltage returns to the learned base idle value. This is also called 0% throttle angle. If this throttle angle is 1% or more at idle, the PCM will assume the engine is actually off idle and raise the engine speed to prevent a closed throttle stall. Note that another sensor using the same 5-volt reference as the TPS can momentarily glitch the reference voltage low. This will cause the TPS to send a lower base idle voltage to the PCM, which the PCM quickly records as the new learned base idle voltage. When the reference voltage returns to 5 volts, the base TPS signal voltage increases to its previous value. The PCM now interprets this as being off idle. This will cause the throttle angle to increase to 1% (or more) and idle the engine at a fast speed.
How hard is it to change a water pump on a 1993 Pontiac Grand Am with the 3.3 Liter motor?
Put a jack under the oil pan with a 2x4 between the pan and the jack face. You will have to take the serpentine belt loose, the idler is below the power steering pump, and then support the engine on the jack and remove the passenger side motor mount. There is an aluminium L-shaped bracket to remove and then a cast iron piece with 4 bolts holding it to the engine. Remove also the alternator, as it will get in the way. Once the motor mount is out you can remove the serpentine belt. Now you will need to remove the bolts holding the stamped serpentine pulley to the water pump, I believe there are 4 of them and I think they are 8 mm. You cannot, however, take the pulley out until the water pump is off. So now you have to take the bolts out of the water pump and pull it out, clean the mating surface for the new pump, and reinstall, just make sure to put the serpentine pulley over the water pump before you try to put the pump back in. On a side note, before you go apeshit with all of this, pull the iginition module and coil pack mounting bracket off the front of the engine and check the bypass hose to see if it has a hole in it before you go right to the water pump. I had this go on the wife's car, and overzealous idiot that I am, I just assumed it was a water pump. Several hours, busted knuckles, and beers later, I discovered that it was a bad hose that cost me 6 bucks and took 15 minutes to install, not the 40 dollar water pump.
Can I put a 3.8L V6 from a 98 Grand Prix in a 97 Grand Am that has a 4 cyl?
it will fit just fine. they are both basically the same cars, just different engines. i am swapping a v8 ls1 from a 2000 trans am into a 2002 v6 firebird. Along with many other things. but the shells are the same. you will probably have to have your computer tuned. Tony, you sir are a dumbass. They are the exact same car except for the engine and some drivetrain components. I have them both, i should know. 98 grand prix Standard Features Bucket Seats Center Console Fog Lights Lighted Entry System Power Brakes Rear Window Defroster Premium Audio System 16 Inch Wheels 3.8L V6 OHV 12V FI Engine Regular Unleaded Fuel Required 4-Speed Automatic Transmission Tachometer Alloy Wheels Traction Control
Why does my brake light fuse keep blowing out?
If none of your three brake lights is working, it's doubtful that all of the individual bulbs have burned out. It's far more likely you have an electrical system problem. It may sound complicated and expensive, but don't worry. Odds are the electrical system trouble is nothing more than a failed brake light system fuse.Each part of the car's electrical system corresponds to a fuse, which protects it from amperage overload; if one electrical component blows out, the rest of the car doesn't get fried. If the fuse fails, electricity can't reach the lights, which may be in fine working order otherwise.Like all fuses, the brake light system fuse can be found in the power distribution centre, which is under the dashboard or tucked away underneath the hood. Never heard of the power distribution centre? It's just the technical name for a fuse box. Using your car's manual, locate the fuse that correlates to the brake lights.You'll need a connect test light for the next step (you can get one at any auto parts store.) Turn your car's ignition to the "on" position, grab the connect test light and attach it to a ground, like the dash or the body of the car, and gently press the tip of the tester to each of the fuse's two ends. Now, press down lightly on the gas pedal. Does the test light illuminate? If so, the fuse is functional, and the problem most likely is a used-up brake light bulb. If, however, the test light illuminates when the connection is only pressed against one side of the fuse, the fuse is faulty. If the test light fails to light at all, regardless of where it's connected to the fuse, you definitely need to replace the fuse.But wait, you're not done -- once you put in a new fuse, you'll need to test it again. If both lights trigger, the fuse is working and the repair is complete. If the new fuse doesn't work while you have a foot on the pedal, the circuit itself is shorted out. That's a more complicated and expensive fix, which will need to be handled by a professional mechanic.Hope it helps.
How to tighten the E-Brake on a 1994 pontiac sunbird LE?
sounds like you're trying to tear it up? i myself have owned 3 sunbirds. they are fine vehicles that'll drive you to the ends of the earth. a better suggestion is if it's a stick, put it in gear when you park it. if it's an automatic, don't worry about it.
Why is transmission fluid in my coolant?
Mike Allen hit the nail on the head.The transmission cooler “lives” inside one of the tanks of your radiator. Most modern radiators have end tanks. Older cars have the tanks on the top and bottom. Regardless, you can tell where the tranny cooler is by looking for a pair of steel lines that enter the tank. The tranny cooler is the only interface where coolant and tranny fluid could possibly be intermixing.In order to fix your problem the radiator will have to be replaced; the tranny cooler is built integral to the radiator and not a separately replaceable component. It will no doubt be strongly suggested you flush and replace the transmission fluid …possibly replace the fluid filter …and flush and replace the coolant. This might cost the better part of $1000 …like 6 or 700 …depending on how expensive the radiator is.And like Mike suggested you need to get it fixed. I’ll go one better …like yesterday.
How hard is it to convert an automatic to manual?
Just for grins, consider the “pro’s” of such a project.You get to take the vehicle off the road and out of use for several months. (Saves on wear and tear.)You get to spend thousands of dollars on the conversion that you otherwise would have blown on something wasteful, (Sadly you will recoup none of it.)The conversion will make a more sporty manual transmission car which will increase its value. (Except, once the conversion becomes known, and you can’t hide it, the resale value goes to virtually zero no matter how well the job was done.)You’ll make a tidy profit on the sales of all the old, used parts you removed. (Anybody want to spend more than a few bucks on a used automatic and a pile of used parts that you can’t evaluate?)Think of all the money you’ll save on ATF. (How much has that cost you in the last 10 years?)Your fuel mileage should increase significantly if you didn’t go to the considerable expense of installing the manual transmission final drive ratio. That involves changing the entire differential, or at least the ring and pinion. (Unfortunately, your new sportier vehicle will now accelerate like a snail.)You get to enjoy the pleasure of shifting for yourself! (With a car that accelerates like a pig and has zero resale value.)
