Question about 2006 Jeep Liberty
Changed spark plugs and installed new fuel injector 1, when I press on the gas to pick up speed the car bucks and when it is idle there is a hard shake and the malfunction indicator light is on. It blinks when I drive but if I am idle it is just a constant light. THese are the codes that come up p301, p0300, p0201
First back track everything that you changed, it seems that either the coil on cylinder 1 is bad or trying to see if fuel is leaking from around the # 1 injector.

Testimonial: "We changed the coil on cylinder 1 no change, no fuel is leaking around injector 1"
CODE 301 IS #1 MISSFIRE 300 IS RANDOM MISS FIRE 201 IS INJECTOR FAULT . I WOULD START BY SWAPPING # 1 INJECTOR WITH SAY # 3 AND SEE IF THE MISSFIRE MOVES TO #3 IF SO REPLACE INJECTOR, IF NOT THERE COULD BE WIREING ISSUES

Check the injector for proper voltage. Check the cam sensor,,,,,DO NOT remove it unless you index it to the block. generally, a malfunction of the sensor will affect all cylinders, PS: you did check to make sure there is adequate spark at #1 plug, right?

douple ck all the ground wiresto engine,trans bell housing ,battery or frame/firewall look for any that may have separated from any pack of wires or broken off eyelets then thightnen all points,,.these grounds are very important to comp/injection controls and can cause a multi code problem like yours.
