busta7777 · 11-29-2011, 05:57 PM

so my car has been doing this for over a month around 3000 miles
1st it was not that bad would only shake at the red lights once or twice every red light so i took it in to the dealer a few weeks later telling them my problem the sa advisor said nothing was wrong no codes, no check engine light, i toled him i couldent belive he didnt feel the shake so one of the mechanics got in my car with me and with my luck the car only shaked once!!
so he said it was nothing big could be spark plugs to come back in one month since my sparkplugs are due at the time in 5k after 3 weeks as in now.
my cars shakes like crazy at every stop sign, red light anytime im not pressing the gas it shake and the idle goes from 600 to 900 it also feel like if it jerks a little no check engine light has came on the one thing i did notice my car went from 17mpg to 9 from one day to another..

my only mods are jb4 map 1
and dci

anyone have any ideas what it could be?

also i notice my car is leaking some oil under were the oil cooler is supposed to be ( since my car doesnt come with a oil cooler )

* my car also has a weird steering wheel light coming on and when i turn the car off it goes away happens 2 times a week i do hear cracking on steering sometimes when i park

Could be injectors, coil packs, or fuel pump.

Definitely check Spark Plugs first, then go from there on all the others e30rus listed above. Maybe in the mean time put in some Techron fuel system cleaner into the gas tank to see if you have a fouled injector, easy and cheap to see if its that.

Any updates the shaking?? Mine recently started shaking at red lights after I changed the spark plugs. After that started happening I took out the new ones and put the old ones back in. Now the car stutters at acceleration and has more vibrations theoughout the car before I took them out and put them back in. Any thoughts or advice? I only have CPO warranty and don't think they'll touch this issue.
