I knew it was cylinders 3 & 5 so I put my OLD plug wires on those cylinders and she runs like a champ. So I think two of my stupid JBA wires with only 20k miles on them is the problem. And also killed two practically new Accel coil packs.
Sound plausable guys???

recovery eta, 4 weeks. 4 weeks of no use of my hand and arm... this sucks. i just hope he doesnt change his mind and say i need surgery. relief cuts for carpol tunnel syndrome is common with crush injuries according to this guy.

I guess your pretty damn lucky then , when you said your arm went threw a 3/4 inch space - I looked at mine and thought NO WAY!!! I couldn't imagine that one..
Well , heal up bud , you gotta get that motor built..

Maybe it's something in the air. Mine kinda did the same thing a little while ago. It was running great then it did that weird freaking sound again and almost stalled out on me - I think its a misfire? Sounds like air spiriting from the left side of the motor every two seconds and it's clunking as well. When all this is going on it wants to stall when I let go but doesn't. ?????
Frick if I know what it is ??? I parked it this time let it idle to see if it would stall - it didn't , but it kept like missing , or it sounded that way.. Anyway I popped the hood , revved it up a few times, held it at 1800 RPM's roughly for a bit , revved it a few more times and it's running good again..
I haven't a clue ..

Maybe thats whats goin on . I have a coolant line running from my thermostat to the TB , my PVC running to the TB and another line that plugs in behind the TB by the IAC .. When I pulled the manifold two of those lines were filled with that soluble looking white oily sh^t , like mayo...
First time I seen that crap in this motor..
