I had this problem for about a month now, but here it goes! I notice that every now and then my truck acts as if it has a miss. It is intermittent and has no signs of anything else! I changed the fuel filter and it was only about half way full. That helped for about a week or so. I made the fuel cap pressure thing out of DIY, and it works, but the pressure valve on top of the tank releases it within 30 seconds or so. I look and look but no leaks. I did however notice the in and out rubber fuel lines at the filter housing are showing signs of dry rot. I don't know, just sucks that it is intermittent and will probably be hard to diag over the net, but what the hell!!! Thanks in advance!!!!!!

Check your oil for fuel. Is it harder to start sometimes after you have driven it for a while? The LB7's are notorious for injectors going bad. They have a 200k warranty

I thought that but everything checks okay. I dont want to pay $100 for return rate readings...

I guess what I mean to say is, has anyone ran across grounded out injectors???
