Hey so today has been just a crappy day...

About a month ago I installed some lowering springs (ultralights) and used the stock shocks and struts. Its been wobbly and had horrible alignment (like if the car was going straight, the steering wheel was like almost diagonal). Well last night I went and raised the car up and put the insulators on in the rear (i had left them out after the install) and after finishing i decided to take my front sway bar off since i heard it doesnt really have much purpose other than cornering, which doesnt bother me...

Then the car drove markedly better than it had, lol ironically since its missing the Front Sway Bar...

Well i take it to goodyear to get the alignment..they charge me $85 and say i need my sway bar... or else its going to go back to **** again... and that i need to do the camber kit (i didnt when i installed)...so my question is, is the sway bar this important to the alignment? That the sway bar allows for the alignment to be corrected....

Also today as i was driving, my car would randomly go down to like 500 or slightly less rpm @ idle (it is tuned and set at 750) it would sound like its is on the verge of stalling out...in neutral! Do you guys know anything that could cause this? I retuned the computer and it still would act likeits about to stall in idle....

 

For your idle issue, try cleaning the throttle body. I did this about two weeks ago and the car really woke up. I was having the same problem as you and a little cleaning took care of it. Good Luck.
p.s. there wasn't much carbon build up but it doesn't take much to mess things up.

 

i have no idea how this got into the 2010 forum.. i definitely clicked the 4.6l general ug.. let me re post this, but thanks also ill try cleaning too. mods can just lock it
