Hello all ! I know I dont have alot of posts, but I have read the newbie guide and have had and worked on my jeep for over a year and a half. I have an adequate knowledge of diesels . I usually read , study and fix my problem . But now I am in some desperate need . I am dealing with something a little weird .
Let me give you the all around about the jeep first . I have done the EHM, unplugged the MAF , cleaned the MAP , racor fuel filter upgrade , kennedy lift pump (that died need new stator) but has been removed has a new hose in place, timing belt replacement at 98000 , waterpump , pulleys, tensioner , new serpentine , new alternator, new rack and pinion.
She is sitting at 104,000 miles now .
Now about the issue I am having , It started a little while ago maybe like a hundred miles ago , I would get a little hiccup right when I started it <it would start fine> then just a small hiccup just a like a fast drop in rpm , not really noticable unless you you are freak about jeep like i am
LOL. Then it seem to progress everytime I started , Like a couple more hiccups very inconsistent. After a a day or two the hiccups got worse , they don't seem to have a pattern either . So I figured a air in fuel issue , so the only thing that I knew where I could possible leaking air is the tank on the quick disconnects. So that was taking care of but the hiccups are there I even bled that racor 4 times . The rpm drops arnt dropping enough to make it die but they are now noticeable and now is a problem that needs to be treated.My guess theory now is possible low compression in a cylinder, possible broken glow plug since I havent gotten there yet
.. possible injector problem . This weekend I am going to get the codes to see if there is anything that might give me clues ... grr I doesnt sounds like rockers or a timing belt slip , but possible a sticking valve?But If any of you have heard this , please let me know .
