|Comment||I forgot to mention I had replaced the fuel and because of the second part of his response was "One other part that you could check out yourself now which could be involved and also is not well sensed by the pcm is the exhaust gas recirculation valve. It is located near the throttle body and is connected to a narrow gauge exhaust pipe that branches off from the center of the right cylinder bank's exhaust manifold. When you find it notice that it has a round top with a vacuum hose and then a flange area between that and the valve proper. Hidden behind that flange is the valve's stem which has a circumferential slot. Insert the tip of a screwdriver in the slot and use that to move the stem back and forth. These is internal spring-action which attempts to close the valve. When the stem gets gummed up due to the exhaust gases that it handles that may keep the valve from closing tightly and then the mixture is too lean which could also cause soot if the mixture is un-burned. So spray some WD-40 on the stem where it enters the valve body and then move the stem back and forth to loosen the action. See if that helps to get it to start again, and ideally also improve the running/soot issue." Made a lot of sense. But because it was hard to access and the day was turning into evening I thought I un plug the vacuum hose to the intake body from the EGR to see if it would make a difference. WALA! The car started. I took it for a test ride and it now runs like a JACKRABIT No bucking No black clouds no stalling and it idles. Thank you Mr.Finston. Now I know what needs to be done. Sincerely Ronald Kassay|
