Check engine came on last saturday and I pulled the codes with my sct tuner for my mustang and it read p0171 and p0100 or something like that. I do know that it is emissions system not ready and bank 1 running lean. cleared the code thinking the maf was dirty. Cleaned it with maf cleaner and cleared the light. Tonight it came back on. I cleared the code and just in idle the code came back on. Also on a side note the tranny is shifting really hard now. Dont know if its a coincedence or not. I need to have the truck fixed and running right by 5am for work or it looks like im walking 7 miles to work. Please help I dont know whats causing it or how to get rid of it.
Double check all vacume hoses you were around. 90 percent of bank lean codes are from a hose that's popped off or freyed. Check around back of blower and around airfilter tube where you were workin.

You may need to re-phrase your first post as I'm having difficulty interpreting what you mean. Do you want the back end to be a different shape or do you just want to be able to spin out in it?
