ok so i did an injector swap a little bit ago been fine..the other day started to skip check engine light clicked on plugged scan tool in: cylinder #4 misfire, opened hood found slight leak at the injector, pulled it apart all new o-rings put back together still set the code and skips, ok..i figured in the off chance i put a bad injector in the same hole i took it all apart swaped injectors around to see if the misfire would follow..it didn't still on #4....i have great spark and the plug isn't fouling and i have injector pulse according to my noid light..PLEASE READ THE WHOLE POST I"M OUT OF IDEAS NOT LOOKING FOR OBVIOUS STUFF...

 

when you checked spark did you do it with plug in the spark plug wire?

 

Gotta swap a new freshly gapped .035 spark plug into #4 to be SURE.

Can't rule out a misfire being caused by something else. That means plug wires, distributor cap. Don't want to chase your tail for $40 worth of ignition parts.

Once you have ruled out plug, wires, cap, injectors, you need to run a compression test on cylinder 4 and may as well do all of them. A good "snapshot in time" on how the engine is doing. Internal problems are often overlooked and they do happen.....

 

all ignition is less then 3months old...compression is at 150lbs 187k on it could be cracked plug gonna try that next..it's not a little skip i have a dead cyl...not gas washed either

 

swap 2 plugs see if it move then

 

i threw a new one in and a new wire still skips gonna just change the cap incase it is cracked or something

 

swap two wires yet

 

ok so i got pissed and threw parts at it and it's fixed..not sure what did it but i'm thinking it had something to do with play in the distributor shaft..i had another dist. with new wires and cap in a box so i threw it on and it's better
