i have a 2002 pontiac sunfire with the 4 cylinder echo tech engine...
for one, can anyone tell me specifically the difference between the echo tech and the regular one? (besides generalizations, like echo tech is better).... and can anyone tell me how i can get it to perform better and such? i am not interested in resale value, just performance: it's my toy.
