Once in a while when I park my Cherokee and return back to it a few minutes later it won't start. It acts like it flooded and I have to hold the petal to the floor and then it will pop and shudder back to life but will have a miss. I start driving it and it dissepears and won't do it for a little while and run perfect. I just did a tune up on it and just ran three cans of seafoam thinking maybe a injector was hanging up. So any suggestions where to start? I noticed it started doing it in the warm weather we have been having.

 

Ttt kinda need help on this everyone

 

Well I checked my oil and it smells like gas so it is indeed flooding.

 

Is the head still good? The 0331 heads are funky...

 

I think so the coolant is all good, never changes level, never has over heated.

 

If it runs rough after a hot restart it's called HEAT SOAK, this is due to vapor lock in the # 3 injector, and maybe more than one injector.It can and will at sometime cause a CEL , or a Flashing CEL.

 

I just made a post about this..and a cure https://www.cherokeeforum.com/f2/eng...issues-128947/

 

I loook forward to tryin this I also have this problem when wheeling only

 

Thank you for your help. I will be doing this trick when I put my 748 injectors in. Right now I have tin foil and it seems to work great. I also started running non ethnol fuel and it made a difference
