thanks again to all the great posts, my car does have the new retrofit sans oxidizer, i kinda was hoping it was there so as to get a new turbo, I reconnected a broken line that appears as it is a BIC pen ink tube, it ran from the intake manifold to the firewall and then back to the ALDA, it ran much better, the gears however are not so smooth when it shifts and second gear sesms to "slam" a little into the next shift, but over all I am really happy with the car, I got it for $3500.00 with about 217,000 miles. I do not know what it is about diesels, but i just really love to drive them, I hope to one day be able to repay everone who was kind enough to offer their help, I am not very mechanically knowledgeable, not yet at least, but I am not afraid to get in their and get my hands dirty. thanks again.
