Much better.

Looks good .

I installed the larger fuel injectors and a fresh set of spark plugs today. Should be going on the chassis dyno for a full tune in about a week or two.

After many delays, it is finally getting tuned tomorrow morning. I will post pictures and dyno results when it is all said and done. I am hoping for at least 370 at the tires.

Well, things didn't go as planned. :( It has a miss, and something is up with the #7 cylinder. I need to do a compression and leak down test. My father is devastated and wants to get rid of the truck.

I hope he changes his mind ,stuff happens all the time .

Right now, he is really upset. I am going to keep him busy with other things in the meantime.

I took a little time today to pop the valve cover and look for any broken valve springs. Everything looks good. I was suspicious of the plug wire, changed that wire. No real change, still flutters at idle. Next is a compression test, and I want to move the injector from that cylinder to another to see if the miss follows it.

It's tucked away in the garage for now.

Spent more time on it yesterday. I started by swapping the injectors for the #1 and #7 cylinders. Sure enough, the miss moved to the #1 cylinder. I got the engine up to temp and the #1 header tube was over 200 degrees cooler than the other seven cylinders. (Verified with an infrared gun, great tool)

New injector is on the way, should fix that problem.

Got the injector swapped in, and installed two fresh plugs in #1 & #7. It's running much better. All I can say is - this thing is going to wear out back tires at an alarming rate.

It seems that I have traded one problem for another. None of the lights are working. Might be a ground wire that we forgot to reconnect when the bed was off. Going to stick it on the lift Tuesday and start tracing wires.
