OK everybody, I pulled the codes tonight and I got the dreaded P1538 code again! I have searched this code from the start and found the info about the IMRC stuff. replaced as mentioned the closest to the rad. quite a while back (before the intake gasket repair) I checked to see about the pulling off the vac. line on one and checking, both seem to be working fine...what is the deal? After it idles for a while the light will come on and bring up that stupid code. It might take a while but it keeps coming back, please help..any ideas?? Nobody seems to have this occur after parts replacement or am I missing something?
