I have a 3800 series II supercharged version. The past few winters I've had the problem of the rpm gauge fluctuating from below 1000 to 2500 and sometimes shuts off if the gas pedal isn't being pushed. This only happens during the winter and normally only when the car hasn't heated up yet. Today it also shut off while waiting on a light and when I turned the key to start it again..it did nothing at all. A few minutes later it turned back on.

My car drives normal then it starts to stall and shuts off. Immediately I restart it and it has strong gas smell threw out the car like it is dumping to much gas and it runs rough. I turn it off let it sit for 2 mins and it runs fine for a couple of miles. I took it in too the shop and they said the ECM is not reading the car.

Unsure how this relates, but headed out of town, stopped to fill up using E85. Still had 1/4 of 89 oct in the tank. 70 miles later engine light comes on and car starts smoking.

Dealer says #4 injector is stuck open & #4 plugs is fouled. Dealer replaced #4 injector & all plugs.
Dealer says #3 injector is now dumping fuel.

What else could cause this problem? I don.t want to pay dealer costs to replace each injector just to find out is was caused by something else.
I'm not familiar with direct injection, but this sounds like it'd have some to do with the engine management system?

My fuel gauge stopped working about a year ago, so I have to calculate my mileage so I don't run out of gas. Next my odometer light started fading and went completely out, but sometimes it comes back on as bright as before. Is there a cause and fix for both of these issues?

Can a broken a/c pump on a 1995 cutlass supreme prevent the car from being drivable?

Could u drive the 95 buick while the ac pump is broken? Will the car start up & drive while the a\c pump is broken?

there is no ignition, the wont get any signal.
the battery is functional and all lights are functional.
i tried to hot-wire the ignition part then the car started then it stopped.

location to add fluid

While all this happening the speedometer, and odometer not working either.

Had it serviced but garage employees couldn't reset it.

Not sure where to begin looking for advice. Does not look like right side been in accident but more like wear and tear. TIA

Replaced belt. Ran fine for about two weeks. Then it came off again. I checked all pulleys to make sure they were not wobbly and spun freely. So I replaced the idler pulley and serpentine belt, again. Ran fine for about 3 or 4 days then the belt came off again.put the belt back on and now the belt comes off with in a minute. But I notice the pulley on the altenator was real hot. Replaced the alternator and got a new idler pulley and new belt. I made sure there was no grease or fluids on all pulleys. I got a new idler pulley, belt and altenator. No pulleys are wobbly every thing clean and dry. And still the belt is coming off. I'm stumped.
