I have got a 2000 GT automatic. Recently it has been shakingat around 37 mph, in fourth gear and pressing on the accelerator lightly, going uphill or level road. The shaking goes away if I take over manual control and down shift to third gear or if I accellerate more. Seems like the logic to down shift is not working quite right. I am running premium gas if that helps. Also, there is no "check engine" light or anything like that. The air filter is ok and i have done an oil change already.

 

please check your spark plugs and fuel filter.

 

Thanks for your response. Where is the fuel filter for the Eclipse? I tried locating itusing the service manual but could not find it.

 

i don't think there is a fuel filter for an eclipse

 

its in the tank, you cant change it seprately. gotta change it with the fuel pump. also does it only do it at part throttle? or does it do it if your at full throttle too?

 

Must be broken piston or cylinder.

 

are you serious?

if you dont know what your talking about, please keep your opinion to yourself

 

Yeah dude ^^

Any check engine light?

 

 

Damnit I looked for that TWICE.
