Top 20 1995 Oldsmobile 88 Questions & Answers

Backfire is a sign you fuel/air mix is wrong. The backfire is the excess fuel burning in the exhaust. Have you got any warning lights on the dash? When was the last time it was last given a major service? A dirty air or fuel filter can cause issues. Check your Air intake and fuel system. It could be starving the engine of air or supplying too much fuel to the injectors. It happens at over 55mph because the engine is working hard and fast pulling a lot of fuel through to do it.

Rust? common problem.

Check fuel filter it might need replacing, then have fuel pump checked.

check fuse for memory, pull it and A/C fuse at same time to reset unit.

This happened to my 95 Royale while driving around town. I checked the battery terminals and one was slightly loose. After tightening it, no more dying.

Are you talking about interior fuse panel? There are two, one is on the driver side under the dash, left of steering column. The other is on passenger side under the dash, you may have to remove right side kick panel, to get at it. I found this info in your owners manual. You can look at your owners manual at my.gm.com Type in year--make--model, then on the owners manual go down to the bottom, find fuse page in the index, sorry, I forgot the page number. It should show you which fuse does what? I don't know if your fuse box cover has a fuse legend or not? Some do.

Most likely lack of lubrication or a failed seat operation switch.

Start with the simple things. Auto parts stores can test your alternator for bad diodes, which if failing can cause this. Next, disconnect battery neg and hook up amp meter, then remove one fuse at a time to find which one changes the reading, then figure out what that fuse powers and check for something like a glove box door loose and not turning off the light. I have even seen a relay sticking on, or one being replaced by the wrong type such that the pins were wrong and the coil was always on. You can find this by feeling the top of each relay with everything turned off. If one is warm or hot you have found the problem.

They will when your battery dies if you don't use the switch

each gear will have a dimple in them. The cam gear dimple will be at the 6 o'clock position and the crank gear dimple will be at the 12 o'clock position when the gears are aligned. http://repairguide.autozone.com/znetrgs/repair_guide_content/en_us/images/0996b43f/80/20/96/59/medium/0996b43f80209659.gif I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Two places I can think of, in the glove box to the right. Or open the door and remove the side panel on the dash.

a bad fuel pump,a plugged fuel filter,running out of gas,someone kinking the line

color does not matter

I would suggest you take it to a lock smith.

Usual way to test is use amp gauge between battery + and battery cable, then pull fuses on at a time to see if the drain goes away. If you find a fuse that fixes the problem, check all circuits associated with that fuse. Check cigar lighter for being shorted/stuck in. check glove box light, trunk light, under hood light for not shuting off.

Start with a process of elimination. Disconnect one tail light unit at the time, and see what happens. You have to work out if the fault is in the light units or in the cable loom. I would suspect the tail lights somehow rather than the dashlights. If the cable looms are very tightly wound up to the plug, unwrap some of the isolation material and visually check for bare wires that can create a short. Have a go.

the gas line rusts out and causes it to leak fuel.

Only Fords have them. Check for power on the fuel pump wire at the gas tank connector with the engine being cranked over. If power there, and no pump action, the pump has failed. If no power, find and check the fuel pump relay - under the hood in the fuse/relay block. First, see if the power feed to the relay is good. One of the terminals that the relay plugs into will have a "hot at all times" power signal. Use a grounded test light, key off, and probe all the terminals-one should show power-will light up the test light. Post back for more help. Good luck.

You need to have the cooling system pressure tested. This will tell you what and where the leaks are. The oil leaks are probably due to age of gaskets and seals. With age comes issues with vacuum lines too.
