Re: ? about egr problem
Just like the TSRM says...
-Diagnosis EGR gas temp below predetermined level during EGR operation. Open circuit in EGR gas temp sensor signal (THG). -Trouble Area EGR system (EGR valve, EGR hose etc.) EGR gas temp sensor circuit EGR gas temp sensor VSV for EGR circuit VSV for EGR ECU First check the obvious, is the plug connected, crusty, broken. Then check the vacc hoses and make sure there not broken/split. If that's not it then check the VSV, it could be bad, and just go down the list. If you still can't find it just don't worry about it, as a matter of fact scrap the entire EGR system all together (unless you have to smog test  ). Good luck with it.
