Vintage Posted February 24, 2011 Share Posted February 24, 2011 I agree, it's not easy to read. But, I understood that when driving along, if he takes his foot off the gas and presses the clutch, the engine stumbles like it's dying and sometimes does shut off. If he pops the clutch, it'll start back up and run just fine. Mine does the same thing when cold, but I think it has to do with whatever gives it trouble starting/running before reaching operating temp. And since I haven't figured that out yet, I doubt I'd be much help. Does yours have any trouble starting or does it idle rough when cold? Link to comment Share on other sites More sharing options...

cz777 Posted February 24, 2011 Author Share Posted February 24, 2011 So what kinda MJ are we talking here? Engine size/year/etc. Does it idle okay when you stop when its doing this? its a 2.5 -1989 mj ok she runs good cold /starts no troubles but when you dive hot or cold slow down below 25 mph AT times cuts out -pop the clutch starts again .... yes this is very baffling one i hope this helps a bit more !

Dechion Posted February 24, 2011 Share Posted February 24, 2011 If I am understanding the situation right I had a similar issue when the winter started to set in here. All I did was increase my idle slightly and the problem went away. Now granted, I probably just compensated for whatever is actually wrong, but I just want to get through the winter. For now I am only working on things that I can't keep limping along until spring. (Like the XJ thats in my garage refusing to start for instance) Link to comment Share on other sites More sharing options...
SubSonic Posted February 24, 2011 Share Posted February 24, 2011 My 90 XJ does that... it needs a fuel pump. Perhaps it's not getting good pressure. Got a gauge? Link to comment Share on other sites More sharing options...

HOrnbrod Posted February 26, 2011 Share Posted February 26, 2011 Glad you found the problem. Sometimes in-tank fuel delivery problems are difficult to diagnose and repair. Good job. :cheers: But just curious for future your posts: Is English a second language for you? Would make it much easier to help you if we knew that. :thumbsup: Link to comment Share on other sites More sharing options...
