Thanks for the info guys... when i went to check the sensor position, i realized that the TB was cracked from the base about half way. It wasnt like that when i put it on... Could the instantaneous 6000RPMs have cracked it? im talking once the key was turned it was at 55K and then bounced to 6K i followed the directions on atropine's and 4 bangers website for installation... and the sensor appeared to be in correctly. I have put the old 2.5L TB back on... i only paid $20 at a junkyard for the 4.0L...
Aside from that, should i worry about any engine damage? I know that the oil wasnt yet in the cylinders, and the engine had been cold for about 2 hours. When i turned it on, and it shop up there, i left it on for maybe close to 15-20 seconds to see if it would drop, but it would only keep climbing. I never pound on my engine, and i change oil at less than 3000 mile intervals. Should i be worried? Thanks
