My truck has all of a sudden started running rough and I'm experiencing high egts and low power. Here is some background - A week ago my truck failed to shut down with the key switch. I pulled the fss and found a chip out of the plunger. I put the fss back in and rigged a temporary shut down cable. Then yesterday it started running rough and low on power. I kept driving a ways until I got to where I could stop and take a look. I found that the fss wire had pulled loose so I reconnected it. Problem solved right? Wrong. While I now have a bit more power, it still running rough and now my get are sky high. Next, I cracked all of the inj lines with the truck running. 1 and 6 had a lot of bubbles so I started looking for air leaks. I found my lift pump outlet line was leaking a bit so I tightened it. I then cracked all of the lines one by one again and got rid of the air in 1 and 6. Still running very rough. Actually no change. Any suggestions?
