    I posted a message about the gas problem. I changed all fuil filters, and new spark plugs.
    And that's not it. What else could it be? Tomorrow I am going to check the timing and check all of the vac hoses. If not we are going to be calling some SHOPS.... I don't wanta but thats the only other option.

    I have noticed smoke from the passanger side exhaust manifold I believe that it could be loseing pressure.
    What do yall think?

    Well starten is fine in nutural its ok but in gear and stoped she is sputtering and some hesatation. I can feel the motor shacken. at freeway speeds its fine it is only at stops. Yesterday I put my finger in the exhaust tail pipe and rubed the inside it came out pretty black.
    So do you think maybe to hi or lean? in the carb. I had it rebuilt 2yrs ago.

    It could also be a vacuum line that's come loose, or a dead EGR valve. Bad idle often stems from EGR problems. Keep us posted as to what you find out.........

    See, now you can go back to that "bad" AM-PM gas : ) (which if you figure 87 octane in a 31 gallon K5 tank, saves you about $3 a fill up compared to other stations)
