Please help!!bad tune? runs like crap this might be a little long but any help would be appreciated!!! first i just dropped a new Ls6 gm crate motor in, mods: LTs, full intake, took all emissions off, had tranny built, had a custom grinded cam from isky cam; 236 243 .598 .610 112+2 LSA, isky dual springs and titanian retainers, harden pushrods, vig 3600 stall, tranny cooler, and may of missed a few small things, o and 80mm bbk tb just dont know if it will idle when i get it going b/c thunder suggested drilling the idle hole twice the sizel
sorry i wasn't very clear on my first thread and missed a few things, i had sneak it at work. i mentioned a pinched vent tube on the tranny, fixed it and tranny seems fine after.it started when i pulled out of a parking lot when it started missing, lost power, treable throttle responce, and wouldnt idle. so i changed my o2 sensers bosch, msd 8.5 spark plug wires, plugs gap .045, tps had correct voltage also. my the motor seemed like it smoothed out a little bit after rerouted the vent tube but still sounds a bit ruff and i cant get it to idle out after changing all that. all my mods are listed above, the tune was just a temparay breakin tune by thunder racing tuner Jeff (great customer service, parts on hand, etc.) but the tune did fine till i reached about 1800 miles. the tune is very rich and im wondering if its not the other (driver) o2 senser wires haven't been damaged(dont think they are). almost forgot the codes; po141pd, p1133pd, p1153pd, and p1153 showed up befofei rerouted the tranny hose and i also reset my computer. main problem is getting going so if anyone has any ideas i would HIGHLY APPRECIATED!!! SORRY SO LONG
thanks steve

If your O2's were lazy they will not throw a code or ses light until they are dead, if they were bad I would check your plugs again, they are probably fouled, doesnt matter if they have only 10 miles on them, never clean carbon fouled plugs replace with new ones..
