Having trouble with my car listed above LT model . Hesitation comes and goes but getting worse , loss of power , misfiring . Check spark plugs, was oil in one of the wells . Cleaned out and changed o-rings and valve cover gasket , flex pipe has been changed , catalytic converter changed. What could be the problem? Also hearing this noise . It comes and goes . Mainly when A/C is on .
