hey i got a '97 eclipse with a 2.0L non turbo, it runs great but when im stoped at a light it feels like the engine is shaking a lil too much and shakes the whole car and it idles at around 800 rpms.....i cleaned out the throttle body a lil with some carb cleaner and changed one of the O2 sensors before the cat and that seemed to help some but it still does it...am i mis-fireing on a cylinder or need a sensor somewhere? im changing the spark plugs and wires tomarrow maybe that will help Can anybody help?

 

most likely a cylinder isnt firing. just chance the plugs and check back

 

hmm..a 97..do you have a check engine light on? are you on stock mounts?

 

i know may be a noobie car question..but since my car is lowered is it normal for the check engine light to come on?

 

The 2.0L non turbo engine is well noted to leak oil down the spark plug tubes through the valve cover tube seals. This can cause a very erratic idle and and misfire under load/no load conditions. Since you're changing your plugs and wires- take a good look down the spark plug tube to see if there is oil down there. I've seen them filled to the top with oil! If this is the case, you'll need to replace your valve cover gasket including the tube seals. Good Luck!

And as candle wires

 

well i changed out the spark plugs and wires....no luck....but ill try the valve cover gasket and the tube seals. Thank for the help guys!!

 

if i would buy a valve cover gasket... it would have the tube seals too right?

 

They don't come together as a kit if that's what you're asking. If you DON"T have any oil leaking into the spark plug tubes- then you don't need to replace them.

no it should not be on.

For the shaking is it auto? it may be a bad torque converter. My dads car has only 80k on it and its doing the same thing. If a cyl was misfiring you would know. The car would bearly run and the check engine light would flash. It could also be the motor mounts like pat said. Those tend to go bad b/c their made from a really crappy rubber.
