Hi, I have a 1992 olds cutlass that is having major stalling problems. When I initially start the car, it idles very high, sometimes it will eventually idle normal but then it stalls. When i am driving down the road, it jerks back and will sometimes stall while driving, it will imediately start again. It is getting worse everyday and I am scared as it always seems to stall when i am at a set of lights or in the turning lane. I have used injector cleaner twice now but it seems to be getting worst. The Cat Converter rattles and when I am having the stalling problems it smells like rotten eggs. I just purchased the car for $700 and it ran excellent untill now (3months). It is in pretty much mint condition and when it was running good, it was idleing very smooth except for the noisey Cat Converter. Any suggestions or fixes would be greatly appreciated
