Rattling/thumping on floorpan, Check Engine (SES) light
Guys,
Just a quick, armchair diagnosis from you, before I go out and jack/lift the front of the 2000 Eldo off the earth and try to squeeze my fat body under there:
About a week a go, I started to smell a slight odor, similar to burning rubber or plastic, coming from the middle to rear of my Eldo; I thought perhaps it might have been a plastic Walmart bag I somehow picked up on the undercarriage while driving, and maybe it was this that I smelled burning...I figured it would soon go away on it's own.
Not so...now a week later, the smell is still there (although slight), but now I've developed a rattling...no, more like a thumping...noise in rapid succession, somewhere on the underside of the car; you can feel it through the floorboards, like it's in direct contact with the body.
Also, the "Check Engine" light starts to flash when I'm pulling up hill, or if I gun the accelerator...if I take it easy and baby the gas pedal, it's not as bad, but it's still there, and it will eventually go off (until the next hill).
And, call it weird, but I can definitely 'feel' a difference it how the car runs...it's not up to it's usual N* par, if that makes any sense.
Any ideas, before I go out Christmas Eve to bust a gut (and my knuckles) under my car? :hmm:
Thanks (as always)!
