Hello everyone!

I'm a new member here. Not new to this forum platform or gm vehicles. I'm very active on the cobaltss forum :icon_blah:

I aquired a very nice, fully loaded trailblazer (blazer) from my mom who passed away this summer. Very sad, but anyway!

It's a 99, 4.3, 4wd, heated two tone seats, 6 disk, sunroof, the works!

But naturally it does have a few little issues...

Mainly: high idle. i'm guessing its the idle air control unit. Read that ones from napa or direct from gm work best?

issues with that:
--idles good sometimes, other times up to 1500
--makes braking... difficult :lol:
--doesn't like to shift right, whether in 2 or 4wd - i.e., will hold 1st gear regaurdless of how hard i'm on the throttle till 3k rpms then shift rather hard.

4wd panel inside doesn't always like to work. i have a new unit. planning to rip the dash off and throw that in

passenger side heated seat button has recessed into the seat.. sure i could figure it out but any easy fixes?

got a good belt squeak. gonna try a little lithium grease either that or i think its the tensioner.

what else... well it has alignment issues, likes to pull to the right. i can hear the passenger side ball joint is out.

i'm at 100k miles; any other maitenance you guys would recommend?

i'm planning on:

-oil change
coolant flush
spark plugs
new belt
trans flush and filter (provided metal shavings aren't holding it together)
new goodyear wrangler tires

thanks any and all for help!

and for your enjoyment... pics! these are the ugliest rims ever btw haha



and my fully bolted cobalt supercharged. doing a ported head and cams over this winter thats why i'm glad to have this lovely winter blazer!

yeah ive been searching around for my throttle issue, gonna go ahead and assume its the idle air control but was hoping for some input

 

update for anyone that had the same issues...

a new throttle position sensor took care of my high idle

a new thermostat fixed my engine not getting operating temp

both of those helped get my fuel mileage back up quite a bit

a new evap canister and cam posi sensor took care of other codes

trucks running great now, besides a massive oil leak from the stupid remote mounted oil filter.
