i had a rough idle, first i thought it was the crank position sensor but after a new one didnt help i removed the idle air control valve and cleaned it. it helped but i eventually needed to replace it. it didnt throw a code either.

maybe you could try it? cleaning is free and its easy to get at

my dads 01 and my 00 SSEIs had bad drivers side wheel bearings and we didnt replace drive shafts either.

everyone here says the wheel hut nuts are one time use. ive had mine off and back on a few times before i knew of this but you may want to keep that in mind

This would cover P0440, P0442, P0446, and P1441.

First I disconnected the hose coming from the motor going to the purge valve and drew a vacuum with my harbor freight pump. The valve normally closed and it kept vacuum. I assume that means its ok.

Next i disconnected the outlet line on the purge ...

yup. gonna tackle it today hopefully get this *dang* code gone for good!

i just posted this what i did and found out

me and another member are having the same problems. and my new gas cap and cleaned filler neck havent helped any. personally im gonna get a vacuum pump from harbor freight and try and check the line, canister, and valves with it.

oh yeah. duh lol the vent valve. i didnt put 2 and 2 together. mines in the same area. i know the fuel line by the filter is pretty rusty but while i was down there changine that i didnt think to check the evap stuff down there...

i was thinking of trying to borrow or buy a little vacuum pump ...

mines throwing the same code. did you diagnose the bad valve? if so how? but then again which one are you talking about? lol the purge or the vent? ill to check the line on my car.

i cleaned my purge valve cause i just didnt want to buy a new one without knowing if was actually bad or not and ...

mine was doing the exact same thing. i thought was the crankshaft position sensor but that wasn;t the case. after i cleaned the idle air control it fixed the issue.

but ive read on here that the CPS gives simaler symptoms. its a semi cheap part but it involves pulling off the harmonic balancer

I had to remove the wheels and hub assemblies from the struts and lower control arms and tie rod ends. remove the cv axels, unbolt the rear trans to subframe mount, front and side trans mount, shift linkage, electrical connectors, bracket on the differential side of the trans, and all hard lines and ...

omg! thank you!

ill check it this weekend

So my car's A/c system has a leak. The sniffer i borrowed didnt start chirping along any of the lines or by the compressor or by a vent with the A/c going also i didnt see any dye in the engine bay so im leaning towards the evaporator leaking.

According to this thread, http://www ...

Update...

I used throttle body cleaner on the IAC... figured better play it safe. and IT worked! When you mention idle speed it was kinda idling slowly id say maybe around 550. I think its supposed to be around 800? Anywho I thought it was the crankshaft position sensor at first but that wasn't ...

Get a new axle nut.

Why would he need a new nut? Just wondering cause I had the axels out during the trans repair (duh) and removed and reinstalled the same one when i replaced a wheel bearing. They didnt seem messed up

I know your car is a year newer but i figured id at least try. lol

My GM manual for my '00 SSEI says the torque for the bracket bolts is 75 ft/lb, the nut attaching the bracket to the mount is 59 ft/lb, and the the 2 nuts attaching the mount to the frame are 52 ft/lb. The top nut is 35 ft/lb.

The ...

it was incredibly easy to make up. and it only cost less than 20 bucks! i think the actual mount is around 60$. I have around 1500 miles on mine and its still holding up.

My car is throwing a PO440 code. been doing it for awhile. I've checked the cap and cleaned up the neck. Im gonna look at the purge valve tomorrow...

Heres what my GM manual says. Maybe you'll find it interesting? Sorry if the pictures are massive. I was worried if i shrunk them the text would be ...

My bonnie has a rough idle when it starts up. I thought it was the crank position sensor and i replaced it. no luck.

so after some more reading i think i could be the IAC valve... i figure id give cleaning it a try. but i have 2 questions

1. it only idles bad after the initial start up. after is ...

I posted about this before but no replys :(

anyway i was just wondering if someone had a picture or a description of the hole i need to drill in the a/c evaporator housing so i can check if the system is leaking there. I have the legit pontiac service manuals and the picture it provides is ...

Update...

replaced the crank position sensor and it solved our issue. the bolts on the pulley are m6 x 1. and were NOT included in the "power master" puller kit i rented from advance auto.

Ug! i forgot to add that ive already replaced the maf. it was throwing a code saying that was bad and a cleaning didnt help. but now its new and it hasnt thrown a code for that.

when i bought the maf cleaner it came with throttle body spray too. i followed instructions from here on for that ...
