I drive a 2000 xj and started about 2weeks ago having very small stutters maybee once aweek.Like sudden loss of fuel .didnt think too much about + there was no engine light.well i put a set of 784 s in and drove fine for a week or two with the same small s hick ups loss of fuel(felt like anyways)until friday it got worse like a big stutters and about 10 mins into the drive home from work still no egine light any help? thanks

 

Ckp failing at engine temp? I just replace the fuel pump and it didnt help by the way

 

So swapped out injectors, fuel pump, and not did much testing to narrow things down a bit?
Expensive 'Modus Operandi' ....

So, for more parts throwing: your CPS can cause the issue as well, as well as CAM sensor, poor ground connections, coil rails issue, aged tune-up items, low battery voltage/quality, etc etc....

 

well the injectors are an upgrade I had planed on doing before hand and the fuel pump was under warranty so I haven't really spent no money yet.Thats what I don't want to do is throw parts at it so should I take the crankshaft sensor and cam sensor and clean them first? any help would be appreciated this is my daily driver. thanks

 

Anybody have any ideas

 

Well i bought a crankshaft sensor from dealership and instaled it and testing now.pray for me..

 

Maybe try the camshaft position sensor?
