I got a 00 QC 4x4 and when ever i put it park the idle jumps around from 700rpms to about 1500 rpms back and forth over and over. when im at a stoplight in drive i can feel the engine wanting to rev but it cant because the gear is holding it, if i dont have my foot on brake with decent pressure it inches forward. what would cause this.

also engine light comes on and it says Emissions system leak or something like that also had a pending code for a power steering pressure sensor. any ideas?

i just bought this truck and love it but its got 137k miles on it so its got some quircks so anyhelp would be great.

Thanks

ps also need now shocks and have never bought them before and dont want to get reemed at the store any advice?

 

whenever the PS press Sens senses pressure it tells the engine to idle up a bit so it doesn't stall. that or an emission problem could cause your idle to wander.

 

Also the front drivers side sits about 1.5 inches lower (space between top of tire and fender) then the other 3 corners do and when i push down on it it squeeks and only that side squeeks so i figured thats the shock thats shot right?

i have 31x10.5 tires on it are those much bigger then stock and what d o they do for me good or bad. like better off roading? worse gas milage? this is my first truck but ive been reading these forums for the last year trying to learn as much as i can and u guys are great

thanks

 

if its not the shock you can raise the t-bar on that side to level it out

 

I have the exact same problem I have cranked the crap out of the torsion bar and it will not level up. The drivers side torsion bar is new cuz the front left of my truck got smashed 2 weeks after I bought it. I wonder if the new one is a cheap pos and has a lower rate than the old pass side one??? any ideas?

 

did you try lowering the other side? If you don't want to lower the one side you could buy a new set of keys for the t-bars that will allow you to raise it even more. But it sounds like there might be something else wrong with it since you maxed the one side out and its still not leveling out. How much lower is it?

 

it's not maxed out, but the left side is almost 2 turns in more than the right side and it's still 1/2" lower.
