when I pull the spark plug wire on #4 cylinder when its running, I cant tell any difference, when I do this on other cylinders, theres a big difference in the way it runs, #4 has 135 pounds of compression,has spark, I changed the cap,rotor,wires,plugs, I checked the plug against the head, it has spark,some one told me a intake manafold leak,I sprayed it with carb cleaner no difference,so I put new intake gaskets in anyway,still the same thing,is there somthing Im missing? timming chain streched? if it was,wouldn't all the valve timming be off? i did check #1 at top dead center and the timming mark was on, ??????
