Hmmm, have you checked the cam? All rockers moving the same? May have some worn lobes. Flat tappet cam?
so.. i think i may have found the problem, tell me if its possible.. my battery died.. i think it has a bad cell or something.. would that cause whats going on?
Ok, now get your receipt and take that crank sensor back to Vato Zone. It's gonna get expensive if you start throwing parts at it just to check (don't ask me how I know ). As Rick said, that thing usually is either working or not. Your old one is apparently good, so that's not it. Get it running, once it's running (and not warmed up yet, for the sake of your hands) unplug the cam sensor from the harness. Go drive it around, log it, and head back to your house. After you do that though, don't forget to plug it back in or it won't start again. I am gonna take a look at your new logs.
I don't think it had to do with your battery, you had great voltage during the 3rd log, but it still did it. One thing that's confusing me is your duty cycle on your injectors, it's only at 22%. That's really low for being on the throttle. I know I've mentioned this already, but you are still not getting full voltage to your tps when you go WOT. If you have floormats, take em out. If I were you, I would try it with the cam sensor unplugged, floormats out, log it. If it still does it, get ahold of Eric at turbotweak and ask him to look at your log. He'll know why your duty cycle is so low (what injectors are in this thing, btw?) After that, I'd say pull the valve covers and roll the engine over to make sure your cam isn't going flat. Hopefully you have been adding ZDDP at oil changes.
also.. i know i had good voltage, thats coming from alternator.. but if the battery had a bad cell, wouldnt that effect all the grounds??
It's doing it right before 4000 rpm, you can see it easily in those logs. Have you tried turning the boost down to see if it still did it with little or no boost?
also one thing i remembered.. i sprayed the engine bay cleaning... i changed my TPS, what else would not like water??
Most of that electrical stuff should be fine unless the connector wasn't sealed off well or there was a bare/frayed wire.
Not without your help. :biggrin: Is the gear that drives the cam sensor worn out? Thats what it looks like. What does the gear on the old cam sensor look like? I tell ya, we have a problem with oiling in the front cover. Thats no doubt. I just changed my cam sensor ring and pin gears. That a comp billet roller cam?
