Engine vibrates in idle real bad


sound like idle speed low idle you need to remove throttle body clean entire throttle body spray cleaner down throttle body bore if cleaning throttle body dont help the dealership has to check it out.a faulty egr valve could be stuck partially open that will cause rough idle and stalling. replace air filter clean fuel injectors.your fuel system could be too lean caused by clogged fuel injectors or weak fuel pump check fuel pressure and also check all intake vacuum hoses make sure pcv valve working should have suction and make sure its in place and the pcv valve hose not cracked open or damaged.

Car is stalling and idleing irradically.


I Would Suggest That You Complete A Engine Cylinder Leak Down Test.....(not A Compression Test But A Leak Down Test) this will tell you if you have internal problems....possible worn rings or a burnt valve(s) I would use a smoke machine to check for vacuum leaks also. Good Luck
