Caio,
I own a 1996 Camry LE V6. It's been a pleasure to own.
I had recently gone to EZ-Lube and got my fuel filter changed. I watched them take out the stock Toyota fuel filter and replace it with a no brand name generic filter. My first gut instinct was, "wow, that generic fuel filter looks WAY smaller than the stock Toyota filter", I figured the size is irrelevant for fuel filters.
So it's been about 1 week, and now the check engine light came on. I "feel" like my engine is not getting the gas it should (the response in terms of acceleration was much better before the generic fuel filter change).
Also, when I listen closely to the engine, at about every so many seconds I hear the engine dropping in RPM when idle. Now, I don't actually see the drop in RPM on the meter, but I can hear it with the hood open.
One other thing I've noticed, there is a slight "whirrrr" sound when I hit the gas. People have told me the check engine light may come on after the car thinks it's time for an oil change, and it can be fixed by "reseting" the oil change counter or something along those lines, but how do I do that?
Regards and TIA
