I just had the head gasket replace and I have been driving it for about 2 days and today the check engine light came on. I am going to check it tomorrow after work. My question is could it be something serious that would damage the engine if I drive it tomorrow.

Thanks

Check the code to find out waht it is.

Then remove your battery contacts for 10 mins, then drive it, if the code comes on you defently have a problem, if it goes away then it was a ghost code.

 

Thanks! I can't get to checking the code till tomorrow afternoon.. Just making sure that I wouldn't damage anything by driving it.

 

well it depends what the code is for silly

 

From the sound of it, I'll bet it's pretty serious... (<<<wiseass)

 

Did you replace the knock sensor wire when the head gaskets were done?

 

Yes I replaced the knock sensor and wire. The code is 71 which is EGR System malfunction. Isn't this for CA only?

 

Possible misrouting of the 1234134 million vacuum hoses

 

thanks.. I will double check all of the lines this weekend when I replace the starter..

 

Did you clean our the EGR valve?
