i have a 98 with the 2.5 V6 when the car is cold it will idle ok. but after it warms up you can't get it to idle for nothing!!!! it throws a map code that says "map reading not changed from start to run". i replaced the map, that didn't help.changed the IAC that didn't work. replaced the maps tassel. that didn't work. full major tune up. that didn't work eather!!!!! its funny once you drive it runs like a champ! but let up off th gas and it will stall. and in order to restart it you have to peddle the gas to get it to start!!! HELP!!!!

 

Examine the EGR if that doesn't close properly it allows in unmetered air ... quick test is to block it off in the rear of the manifold if the car idles theres the trouble

 

well that was it!!!! blocked off the EGR and the idle cleared right up!! it even passed a VA state inspection!!! thanks!!

 

No Problem ... You CAN disassemble and try cleaning it , the valve seats get crapped up and doesn't seal ... Or get a new one

 

Can you totally eliminate the EGR system in a 95 2.0L? Are there any nasty effects in the short or long term if it's done?

 

blocking off the egr is easy ... but it can at times cause a CEL ...

 

What are the pros and cons of blocking that off? I can deal with a CEL as long as I'm not hurtin my baby...

 

Really no Cons except the CEL and some never get one . more emissions
Pro's intake stays cleaner

 

Is there a sticky on how to do that or steps to do it anywhere? Thanks in advance...

 

on the 2.5 I just pull the gasket/pipe off the rear and made a plug out of .... a beer can ....then reinstalled
