Thanks once again for your reply and the images you sent, they were super helpful and informative.
Before this last message you sent, I noticed that the vacuum hose connected to the Q port of the EGR modulator was hanging loose, but because I didn't know where to connect it, I left it like that. But after seeing the schematic diagram of the EGR valve connections in one of the pictures you sent, I discovered that the hose was to be plugged into the VSV, so I plugged it back in. Also, I removed the EGR valve to check it's condition, it was still working, but had a lot of carbon deposits, so I cleaned it up and installed it back in.
I did all these last night, so I'm yet to test it out. I will go ahead and test it today and get right back to you.
Thank you so much, you've been of immense help to me, I really appreciate.
