i had an 86 300zx that was misfireing due to build up in the injectors, and i put a quart of marvel in with half of a tank of gas, didn't have time to pull the injectors and clean them properly. i did this as i was leaveing my old job,and had about a 30 min commute to get home.as i was driving i slowley noticed a difference in the performance of the car.when i got home and parked it i left the engine on for a minuit and opened the hood, i had noticed my idle was a lot smoother, it seemed to be running fine. i ate dinner and watched some tv for a while giving the car time to cool. when i went back out side to put it in the garage it instantly started(a first for the car) and put it in the garage. i pulled one of the injectors and was going to clean it and the lower tip allmost looked new so i just put it back and the car continued to run ok. about a week later i used the sea foam in the intake(put a vacume line in the sea foam ). *****very important to follow the directions EXACTLY******. when i started the car the smell was horrible(do it in an open parkinglot, not your front yard, your neighbors will never forgive the horrible smell)the car didn't have a cat(the first thing i do when i get ac car ,but if i get pulled i bought it like that ) and a free flow exhaust and i actually saw small carbon flakes comeing out.the car ran like it had just recieved a major tuneup! that was enough proof for me, i have done the same treatment on every car i have owned and never had anything but good results. all for well under $20
