i was reading another thread on rough ideling and hard starts...

The fix was cleaning the ERG with throttle body cleaner ...

i just dont know where the ERG is located or what it looks like ...

my 98 blazer idles a little rough .. it has about 145k on it and its super strong ...

just idels a little rough .. so im guessin the ERG really needs to be cleaned ..

i put the key in the ignition and turn and it starts up right away but it starts hard ... any advice ??

thanks

The ERG is located in the front center of your intake. Here is a pic of what it looks like.

ok so went to oriellys

got some seafoam ... it says you can clean airintake to get some carbon out with the seafoam...

i was told to find a vacuum hose and put in down into the can of seafoam and slightly rev the engine cause it will want to die out ...

i thought i found a vacuum line but when i told it off nothing reallly happend sooo now i need to know where the vacuum line is and is it safe to use this seafoam ???

and would anyone recomend another way to clean carbon out ..

ive heard i might see a lot of white smoke ???

You can try Water Cylinder Decarbonizing. Heres a step by step. http://www.automotiveforums.com/vbul...d.php?t=283211
This works well.

ok soo where is the pcv located what does it look like ... none of those vids work..

You can prevent the carbon build up from going up in the EGR valve,some parts stores sell an EGR valve gasket with a filter in it and Carquest is one.I do not remember the part number out of my head.

MT-2500

You need to remove the EGR valve to clean it or check for carbon ball in it.

ok so ... i know where its located .. do i need to just take the 2 bolts off and take the whole component off ....???

or is there an easier way ...

i mean is what i need to clean under those 2 bolts ??

surfnobc2

ok cleaned it a little i guess ... there was lots of carbon in it ... no little carbon ball or anything ....

so should i try steam cleaning it through the pcv ... and i still have no idea what even looks like or where it is ...

When cleaning the ERG make sure that there is nothing obstructing and the plunger moves freely in and out. Once your done that reinstall the ERG with a new gasket and reconnect the wiring harness. Start her up and let us know how she is running.

Use a screened gasket for the EGR valve to keep the large pieces of carbon out. NAPA sells them if your regular parts store doesn't

surfnobc2

alright guys .. did it ...

runs about the same ...

im thinking its a spark plug issue ... possibly a cap .. checked plugs and stuff .. look good ..

the plunger in the ERG was moving freely ..

i think im looking to hard

how do i check my distributor cap ... ??? can i just pull it off ... make sure the wires go back in the same place

Gabe25

OK, You have 2 torx T-20 on the front and rear of the base of the cap. The easies way is to remove the plug wires on the right hand side first. Make sure you tag them. Closest to the front is 1, then 3, and 5 closest to the firewall. Now remove the 2 torx screws. Be careful not to drop them. Then gently lift the cap and flip upside down. Inspect the cap and rotor. Replace as needed. Reinstall in reverse. Check out this thread. Got some great pic on the distributor. http://www.automotiveforums.com/vbul...istributor+cap
