ok last week im having trouble with the car. stall, ten mins later its fine. put in a new fuel pump, runs like a top. now it's got a new trick.im out for a drive today and she is acting weird. i come to a stop and while it is idleing it is shuttering.put it in park or neutral and the shuttering is so slight that you wouldent feel it if u wernt looking for it. put it back in drive amd i give it a little gas it goes away but i know that's to much gas cuz if i go park drive it hits to hard. so i head home and pop the hood and what do i find. first thing i see as soon as i pop the hood is the cap on the coolent overflow is gone, the one where the censor goes if you have it. that seems odd to me so i go and glance in and it's looking real dirty, and oily. i do a finger test and it feels oily. just to be sure a get a little out, mix it with water and it dont mix, just floats on top. check the oil and it is a little low for being changed less than a week ago hmmmm. now most see where this is leading to. just a couple things are throwing me off. the shuttering just started so if the hg just blew then where did it find dirty oil its prolly got less than 500km on that oil. there seem to be no other signs of hg failure. temp stays normal, power seems normal, exhaust seems normal. ive only been driving the car a month and the engine is supposed to have only 10000km on it. my gut is telling me that the hg has been blown scence i got it, i never new because i coudent see clearly into the overflow and it has no other symptoms and the shutter is from somthing all together different. but i would like to hear what you guys think. im gonna run the codes tomorrow.
