Okay so... I have a 1998 Toyota Camry with about 90k miles on it, and here lately it has been acting up a bit. It seems whenever I drive it a little bit and them come to a red light or a chance where I have to come to a complete stop, the rpm meter fluctuates up and down and the car rattles a little bit. It almost feels like the car is going to stall out but its an auto transmission. This only recently started happening, and seems to have a connection somewhat to the AC since its summer and it doesn't do it in the winter. It also seems to happen a bit more when I am on inclines or going over hills. I am no mechanic but I did have a Toyota specialist look at it and he couldn't find anything mechanical wrong the last time it happened a few years ago. Someone mentioned to me it might be the fuel filter which is due to be changed, and I plan on changing the air filter as well, but this has been happening a lot more recently and I just want any suggestions or ideas as to what I can do or what it could be? Thanks in advance. =/
