Do you have a scanner that can read the misfire counters???? I would be interested to see which cylinders are misfiring.

 

My friend who is a tech used his, couldn't find any misfire data at all................ Also not getting any codes.

 

Yeah. It seems the V-10 has issues with that. I had a dead miss on one cylinder, and it never set a code....... the scanner I had wouldn't read much in the way of data.... (waste of 50 bucks....) so, no idea if the PCM was noticing or not.

 

Well, think I found the problem. The only way this passed the smoke test was for the leak to be to the valley.

 

Is that actually a bolt hole for the intake? Or just an alignment pin?

 

If you look above and just to the left of the bolt hole you can see the smaller hole for the alignment pin.

 

Interesting. I suppose, with the mile long intake, that was pretty much a requirement to get things to align properly on assembly......

 

Well it still isn't fixed. It is improved, now it doesn't die when stopping at all but it is still mis-firing and popping if I don't let it stabilize the idle before taking back off. I can hear it mis-fire in the exhaust, its not the most consistent thing but kind of. I have poor throttle response and power. I pulled a couple plugs, seems lean to me. Both cyl 2 and 4 looked identical. I didn't pull any others yet. It is on a safe testing tune right now.

 

Clogged injectors??

 

I don't know at this point. I picked up a spark tester and I am going to also do a compression check.
