I got in an accident recently where my radiator had to be replaced and a got a bent ac condensor. since then the car has a check engine light and after driving around for a while, it idles very low, like the needle is on the 0 almost. any reason what could be causing this? It dosn't over heat or anything it just idles really low and shakes like your engaging the clutc without giving it gas in 1st. car is a 00 lx y7

 

i just checked cel and its primary oxy heater
