My wife's 93 Buick LaSabre has been a great car. It has 185,000 miles on it. The engine is the 3800. Last week it started running badly like a plug or two was miss firing. The next morning was a cold and wet one and it would not start. It had a strong smell of gas.
I changed all the plug and found a couple we blackened over. It did not look like oil and I don't think it burns any oil just has a few leaks here and there. I put a can of fuel injector cleaner it the gas tank and all seemed well. One day later on her way back home it stalled out 5 times in 20 miles and she said she could smell gas.
Could it need some fuel injectors replaced? They are costly and the car is really not worth much but we do still like it. If you think its fuel injectors is it possible to clean them?
TIA
