have to think that you cam is out of time, especially with the rough running below 1500......

 

this is what we got from the timing chain, to me that does not look one tooth off, what do you guys think? The only thing is the chain is tight on the right side, in the manual it shows the left side the chain is tight, is that a possibility? It didn't say anything about chain slack being a importance, but at this point I have no idea what else can this be.

I ordered brand new injectors but they will be here roughly next week, so I was thinking I could have this all back together by the time they arrive.

 

Ok, so after swapping the wires, coils, unplugging the maf and the oxygen sensors, did the misfires stay on the same cylinders? I assume they did. So you swapped known good plug wires and plugs from cylinders without codes to cylinders with codes, correct? Cleared code, they came back, on the same cylinders? Same thing on the coils? If so, there few more diagnostics I would recommend before throwing more parts at it.

1. Let's see photographs of the spark plug tips - all 8 of them. If you have an injector issue we should be able to see one or two lean cylinders on the plugs.
2. You can swap injectors to different locations just like spark plugs, if the injectors are bad the misfire should follow the injector.
3. Check the compression on the cylinders misfiring, if the compression is low the ECU will detect a misfire. Possible causes:

1. Valves not seating
2. Rings not seating/gaps aligned/rings broken
3. Cam lobe wiped out during break in.

4. Remove the valve covers and watch the valves open and close for each cylinder while spinning it over. If you remove all the plugs it should spin pretty easy with the starter or by hand. Because it is fully rebuilt it is conceivable that on break in one or more of the cam lobes got wiped out by the lifter and that cylinder does not have adequate compression.

 

So I finally figured it out, turns out I had a bent intake valve on cylinder 4. Must of happened when I was doing timing since I put the rocker arms on before doing timing (I must of got excited and completely forgot that it was a interference motor, pretty stupid mistake if I do say so myself). Replaced with my old heads got those all set and now it is running like a champ!
