1991 Oldsmobile Cutlass Supreme Questions & Answers
Hi I have a 1991
My 3.4 liter 91 Cutlass Supreme has similar problem when warm the engine misses (car jerks). But its fine at idle and without any accelerator pressure. The SERVICE ENGINE light also comes on intermittantly. I am going to test the ignition coils.
Need a fuse box diagram for 1991 Olds Cutlass
You can go to a nearby parts store and purchase a Haynes automotive reference guide and it contains all the different diagrams that would need. On the front of the book it would say 1990-94 lumina cutlass etc.
91 oldsmobile cutlass supreme heater core replacement
Cores come in 2 general design locations--in dash and under hood. Both are replaceable but the dash tends to be more problematic as it may include removing the entire dash assembly. under-hood may require opening up the air conditioner system to access the air plenum. Search Youtube for "how to" videos to get a good idea of knowledge and skills required.
The shop manual is available from auto part supply stores for around $30 and in some public libraries. You may have a split or lose hose and not the core itself. Suggest you first rent borrow or buy a remote inspection camera to locate exact leak location.
1991 oldsmobile cutlass supreme gas gauge
Frequently the float/in tank fuel pump assembly which is mounted in the gas tank is to blame for this. As you can see from the attached picture it is an all in one unit. It is something you might want an auto shop to handle. I have replaced some that are accessible from under the trunk mat but it does involve fuel so I would recommend a mechanic to replace it.
91 olds cutlass supreme runs rough and wont stay idle.
If your vehicle is fuel injected I would say you have a blown fuel regulator. This would cause excess fuel into the cylinders (flooding) causing a miss and coughing and also blow fuel into the air breather. If will also cause the vehicle to run poorly and could cause the vehicle to stall. Also to much fuel on startup can flood the cylinders and cause the vehicle to no start.

91 olds cutt supreme 4 door 3.1 multi port v6
I had an '89 Mustang the had cracks in my fuel injectors, no fuses on them but that's Ford and GM's Difference. While I was looking in junkyards for my fuel injectors to replace them, I was also looking for a GM alternator. I noticed that there were a lot of GM cars that had silicone coated over the Fuel injectors on many of the V6 model Cars! I determined that this was their solution, Silicone's cheap and you have little to loose by trying this. New fuel injectors can be very expensive and you'll never find any good used ones from what I saw, 75 percent had this done to them and the other 25 were probably bad but didn't know how to patch them up.
Where is and how do I replace the blower motor/fan assembly?
Depending on the type of car you have, it can be very easy or very difficult. The easy ones will have a circular metal plate on the firewall with about 10 very small screws around its circumference. Protruding from that plate will also be a small usually black can looking object about the size of a soup can. This is the fan motor. Just disconnect positive terminal on battery before starting, then remove the series of small screws. They are usually a hex type screw, not a slotted. The whole assembly will lift out and the replacement will look just like this one you've removed.
That's the easy one... the difficult ones are under the dash, passenger side inside the heater box. They look like the one I described previously, but usually require a lot more disassembly of surrounding components.
Best of luck!
What should the ohms read good on injectors for an oldsmobile 3.3 V6?
Use care in removing the fuel injectors to prevent damage to the electrical connector pins on the injector and the nozzle. The fuel injector is serviced as a complete assembly only and should not be immersed in any kind of cleaner. Support the fuel rail to avoid damaging other components while removing the injector. Be sure to note that different injectors are calibrated for different flow rates. When ordering new fuel injectors, be sure to order the identical part number that is inscribed on the bottom of the old injector.
