hi - guys - i need some help - last week i got my budget Y-pipe installed and everytime i push her hard I get 0503(egr temp sensor)
I reset the ecu and it was fine for few days was ok until i pushed her hard again on expressway - got the 0503 again - so I reset the ecu again and than check engine light start blinking on me like crazy
and car would not shift in to 4th gear !!!!!! I know it went to so called "fail safe mode "
I really need some help - I don't know where to start - should I replace the egr temp sensor , or erg valve or what ?????
any ideas would be greatly appreciated
thanks
Nick
