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???

yeah. doc says its all soft tissue damage. meaning contusions, massive swelling and massive bruising. they gave me perkocet. a freaking narcotic and it rips my stomach up good.
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.

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..
