I should have said "when you see the numbers change, thats when it happens". :) Actually, it varies on ambient temperature but you are right, I was giving you a rough number.
Developed a knock.There were many good suggestions in posts that your links lead to but there weren't enough questions imo. Let's try to make sure there's a comprehensive picture of what's going on.
Why was the original engine replaced? Did this outfit run fine prior to the swap? Were you the owner before the engine replacement? Was the engine replaced at a shop?
Ran as fine as a TBI can run.
I was the owner
I replaced the engine.
Is the picture of the invoice from Sunwest Engines for your engine? Did you choose this company to supply the engine? Why? Did you select this part number for the engine or was it recommended for you? Did you get the base cam or the optional RV cam?
My engine invoice
I chose them on reviews
Parts were what they gave me
Base cam
0 wont work, its a dog. I am at 6 now, have been at 4 and 8 as well. 6 seems to be nice. I have done the 0 thing though and its the same.Is your distributor now set at the value indicated on the sticker under the hood? I believe it should be 0 degrees? Or did you leave it at 6 degrees?
I asked the engine people about it, they said it was correct. The cam/crank gear were dot to dot when I put the cover on. I think we pulled a plug and did the TDC thing too.Have you ever confirmed that the timing mark is correct for the timing tab? Not that the part number is correct, but that the piston is at TDC when the mark indicates TDC.
Fuel pressure is to spec, injectors were the ones I sent to be cleaned and tended to. I do believe the numbers are correct. Its been a while and I am 57 so.....Have you ever measured the fuel pressure? You said the injectors were rebuilt. Have you ever confirmed you weren't sent the wrong injectors?
I am using this: http://www.1320electronics.com/12pin_ALDL_BT_MK2.html and his ALDL app. I have all sorts of logs, long drives, hot weather, etc: [brace yourself] https://drive.google.com/open?id=0B5...ndnMmlqcDJEVDAWhat are you using to scan and save the computer data? Have you ever recorded computer data while driving? A recording of computer from a spell on the highway when the truck is running correctly could be helpful.
Its running rich because it smokes, you can smell fuel, and my experience tells me. No cat, new o2 sensor. Completely, that is when I stopped logging, when it cleared up to normal.You say the problem is rich running. Is this because you can smell fuel fuel from the exhaust? Anything else? Do you have a cat installed? Does the problem clear up completely when the engine runs better?
I'm a ranch guy, the big city is 120 miles. We both know what thats like. I'm a pretty good wrench, until you through electronics in the mix. Hope I wasnt short with you but I thought I would be brief and to the point. I appreciate your input.BTW, I made a living working on these trucks in a GM dealership in eastern MT when they brand new. I also worked nights and weekends repairing equipment on the ranches in the surrounding county. Unlike folks that live near town, I know what it's like when a trip to the store for a tool or a part is an all day affair.
