96 oldsmobile cutlass supreme, have a few issues. First we have an oil leak that we cannot locate, it seems to spray on everything, it is even up on the felt under the hood the plastic radiator overflow is coated thickly in oil pretty much everything on the left side(when looking at the engine)is coated in oil. And we cannot figue out where it is coming from. And then today all of a sudden the car started smoking BAD. It was coming from the exhaust and from under the hood. do you know what might have caused this? It had a bad oil smell to it, and it quit doing it after about 20 minutesof driving. But we stopped and looked at the engine to see if we could figure it out, but we have NO IDEA! Please help!! Also, we have power issues. Sometimes the car acts like it isn't getting any gas. We changed the fuel filter and the spark plug wires. It seemed better for a while but then the problem came back. Again we have NO IDEA! Please Help!

Check for fuses/power/ground to the engine computer (or injector drive computer) whatever the case is.

Spark, fuel pump, and starter all are independant of the fuel injection computer.

Either the computer itself has gone bad, or it is not receiving power or ground, or wiring to the injectors might be bad...

It's not to hard to do, just have to lay upside down in your pas. floorboard, remove plastic panels under gloove box with small nut drivers,(can't remember size) then there are three hex head screws holding on the blowerplus the wireing connector, anf it has a wierd rubber gasket, hope this helps.

SOURCE: when i start my car you smell gas ,and it smoke.

HTML clipboard If you can smell gas ONLY when the engine is running, then the gas didn't get burned completely. It could be the combination of the computer, oxygen sensors, and/or catalytic converter is going bad. If you could smell gas when it's parked, you might want to take it to a mechanic to have your gas line checked for leaks and for pressure test. Here's a website that talk a little about gas smell www.mycarsmellsbad.com good luck.

Sounds like a RFID issue. Your key most likely has a chip inside of it. Most of the time people will have multiple keys on their key chain that can cause interference with the receiver in your steering column. Try using the one ignition key to start.

High NOX readings indicate a somewhat lean condition IE: hot exhaust. Possible causes are cracked and leaking vacuum lines or lazy oxygen sensors. If possible have a reputable garage with engine electronics scanner services check the sensor to see if its helping to create the lean condition
