Question about 1988 Cadillac Brougham

1 Answer

I have a 1988 Cadilac Brougham 5 L. (307 olds?) with electronic advancement of distributer. It was running fine until I replaced the throdle position sensor. Now it has problems while cold (stalls) and always truble with acceleration. With coller weather I now have to keep pumping the gas to keep it from lossing spead. It runs fine at idle and once it gets air flow, at full throdle. But anything inbetween problems. I have to punp the throdle to accelerater or maintain speed because the engen bogs down. I have to double pump off the line or it will stall. Any thoughts? timing? Vacume system? Running lean - how to fix?

    How do you do that?

  • Anonymous Oct 14, 2010

    You need a volt meter,back probe TPS sensor wire,loosen sensor,and adjust to what ever is required at closed throttle.
    I don't have that info. About a half volt closed and near full 4.8 volt full open

    thank you I will try that. I did disconect the tps harness and it did start to run better. Guess I will have to find out exactly what the voltage should be. Thanks again.

Chirping sound on 1988 cadillac brougham as I drive it. Already replaced everything on wheel.

Check the disc brake pad thickness ( both sides of each rotor ) there is a small metal bit that when the pads are unsafe the bit scratches on the rotor to let you know to replace the pads.

Car stalls when engine is warm

Your TPS switch is bad. It is caled Throudle Pision Sencer. It is on the side of the throdle body and has two wires going to it. It is not reading where the throdle is so therefor it stalls.

1988 GMC pickup 4x4 350 engine its hard starting and will not idle i gave it a full tune up even a new fuel filter ive checked and changed all sencors on the motor

Do a compression test. The pistons and rings may not seal enough anymore. Try push-starting it in 2nd gear. When you push it ,it will turn the engine faster and build up more compression, enabling combustion to take place. Aslso check if the fuel pressure regulator is not leaking through the vacuum hose, causing it to flood.

I have a vibration problem in my 1988 cadilac brougham rear wheel drive with 24,000 original miles.Put on 4 new cooper tires the car had 1987 vintage tires on. that didnot fix it the driveshaft had a dried...

The age of your vehicle guarantee's a vacuum leak. It may sound silly but the truth is rubber grommets, and hose's shrink and dry out over time and the harsh environment under the hood makes it worse. Check all vacuum lines and fittings attached to the intake manifold, valve covers (pcv valve), and be sure to check for a vacuum fitting on top of the intake just behind the throttle body. Does it fit tight in the hole? You can seal loose fittings with a high-temp RTV (Red) silicone sealant/adhesive. Several small leaks add up and your engine, heat/AC, and transmission will be all to glad to tell you about it.

How old is the transmission fluid?
When they installed the new tires did they check for a bent wheel? Take it back!!
Engine and Transmission mounts are rubber connected steel plates. Maybe one has seperated or broken.
How old are the plugs and wires? The vibration could be a miss-fire. With plug wires, it's the age, not the miles. Get a set from GM, not China. This will get you started....

Problem with the 1988 Toyota Pickup"

So, I first assumed that is was a pickup. However by your vehicle description in the body of your question, you have an older vehicle with a different engine type. You might want to update the site title to your question.

The truck I have is 1987 Toyota Pick up with a 22R engine with electronic ignition. So I might not have the specifics for your vehicle but I would suggest that you set your point gaps to the specific gap the manufacturer suggest for your 82. This gap has a lot to do with the timing. On my truck, it is breaker less electronic, but I still have to set the distributer position to 8 degrees BTDC (Before top dead center). I use a timing light connected to the #1 sparkplug wire. I also have to disable the vacuum advance by disconnecting the vacuum line and plugging it so the engine does not run rough while doing my checks. I also have to make sure the distributer mechanical advance is also not interfering with my measurement. I have to keep the RPM less than 750 otherwise the mechanical advance will advance the rotor position by 5 degrees. For my vehicle, the vacuum and mechanical advance together can position the rotor to (8 + 5 + 5 = 18 degrees BTDC).

For your vehicle, I would make sure your advance is working and is in the "relaxed" position and not interfering with your timing measurement. If you have a vacuum line going to your distributer, you might have a vacuum advance as well. You can check this by using the timing light and observe the position of your crankshaft mark as you increase the engine rpm. You should see the crankshaft pulley mark move in relation to your marks on the engine block. If it does not, that might be why your engine is weak. Many times my mechanical and vacuum advance would not work and my engine performance suffered. My distributer electronic ignition sensor sits on a plate attached to ball bearing ring surrounding the shaft. The mechanical advance was activated by spinning weights that would adjust the position of the sensor the faster the distributer shaft spins. When my distributer would get dusty and dirty and the bearings would clog and not roll too well. The vacuum advance also moves this plate, but independent from the mechanical. It too would get stuck and not move the advance as far as needed for engine speed or load.

Since you have your distributer out, make sure it is fully clean and if you have mechanical and vacuum advances, that they are clean, free moving and in working order. I would set your point gap at the high point of the lobes. Also, make you
