THOUROUGHLY cleaned egr vlave, throttle body, replaced knock sensor and cleaned ivac still getting the code... i really dont want to do that whole job over.. anyidea...been two weeks with no inspection because of thiis code

 

Did you clear the code?

 

yes it came back in 30miles

 

did you clean the small tube?

 

cleaned the topone in the back connected to the ivac

 

repost...My P0400, 0302 cel was solved by replacing the EGR solemoid valve ( green Connector ). I replaced it, but took apart and cleaned the old one and now that one is working fine too. Easy to clean, only one moving part inside, a spring and 2 O rings. Hard part is taking it out and putting it back in. So save some money and try cleaning it first...david

 

can you tell me exactly where it is please?

 

I type really slow...so here are some links...you can test it first to see if it clicks before removing it. Also if you have a "99 the this is not your problem. GL
