Hi dr,----OK,read your last post about the parts you replaced,you have an OBD 2 diagnostic system. By now with all the misfires you have been getting your "check engine light" has to be on by now,300 misfires or more will turn on the light & set a code for that cylinder. If you don't have your own OBD2 tester, go to the local Autozone & have them read the code(s),write them down & have them clear the codes. Example PO301= #1cyl,P0303= #3cyl,etc,last digit tells you what cylinder is misfiring.Once the codes are cleared, the ECM will start giving that injector a pulse width again,if it still sees a misfire it will turn off that injector to protect the CAT convertor.You said you had the plugs out again, what did you see at the electrodes,what color fouling ,wet with gas ?,black & sooty?,what number cylinders had fouling??.When I hear that you have a ticking noise that can be a few things in the valve train system but we need to find out what cylinder has the misfires first. Please reply------ Ray
