1992 Pontiac Sunbird Fuel System Parts

I wasn't sure what to expect when I bought this for my 2001 Buick LeSabre! I saw all the benefits from this product on CARiD so I thought well it's possible. I bought it and installed it. I did not notice any gains at all for months. Months went by and still nothing. About the 8th month after the install I started noticing a lot of white smoke coming from my tail pipe. I thought that was odd because it wasn't cold out and my car doesn't poor white smoke out of the tailpipe when it's warm out. The smoke would be more noticeable at first start up usually in the mornings. Then I started having problems with my transmission. It seems like the transmission was going bad because it was whinning shifting hard and that was odd because if a transmission was going bad you'll slowly notice it over time and not it one day like I did. A week went by and the transmission finally settled in to it's new realm. There were new dimensions to the engine that the computer had to pick up on as the catalyst was starting to work. I thought it's about time. The product says give your car ten operating hours before noticing anything. I went months and didn't see a thing but the whole time behind the scenes the fitch fuel catalyst was working behind the scenes. Amazing. My car sounds great. My engine hums like it's new. Every now and then I'll see the white smoke.
