Hey, I bought an 04 cavalier 1 month ago from an old guy. The car has 4700 miles on it right now and i bought it with 3700. Ive just put some lucas injector cleaner in the gas tank. When I bought the car he informed me that it had been sitting for 1.5 years in back of his garage. The car runs great and looks great. The only thing ive done was an oil change, put in a k&n and run some 93 through it. I was wondering if it would be worth running seafoam in my vaccum line. Ive done it to my truck and a bunch of my buddies vehicles and it made them run so much better. I was just wondering if it would be worth trying to clean out the exhaust and the top end of the motor, or should i just wait some more miles.

Well matt cheche, You could do it if you want too, 4700 miles is still pretty new, They say every 5,000 miles it should be done.

How do you put it in the vacum line ? I would like to try it. Thanx

Define old? LOL. I use seafoam in the gas tank every other fillup. Seems to work.

Rino De Luca , all you got to do is pour sea foam into a plastic spray bottle, By feathering youre throttle spray sea foam into youre TB, or remove the brake booster hose from the booster while the car is running pour a small amount the vac line. Or put 1/3 of a cup in youre gas tank.
