[QUOTE="Dan04COBRA, post: 15894615, member: 38156"] Had some overheating issues I solved and about a week later PO174 lean popped up. At 180 degrees, my aeroforce shows Short Trim B1 4.6 Short Trim B1 96.1% Both readings are at 2500. At idle its B1 -0.07 100% Bank 2 has similar short trim readings Bank 2 is reading virtually all the time, idle. 2500rpm, driving etc Long Trim 25.5 100% The o2 millivolt on my aeroforce shows b1 o2 fluctuating from 66 up to 1000 at idle All over the place. B2 o2 hovers around 260-300 at idle. I've searched for vac leaks and haven't found anything yet. Had a suspect hose on the throttle body and replaced it. Cleared code and it comes back after about 20 miles. No funny idle, no misfire. [/QUOTE]
