So I replaced the fuel pump last week.. was fine for a day or 2 then
it started having a problem of running rough right off idle and it looses
a little power at high rpms like a miss. Also when I let of the gas even after its warm it lets off a bunch of little back fires. Im thinken since I changed out the fuel pump it effected the CO and its now to rich. yesterday after work I replaced the fuel filter and on sunday I replaced the aux
air regulator, warm up regulator, and all the injectors. Im thinken I have to
adjust the co a little counter clock-wise to lean it out or replace the acclumalator and do the quantative test on fuel dizzy with the injectors by lifting the sensor plate.....

A question I have is Is it more likely just to be running to rich since I chenged fuel pumps. I cant send it to the shop cause there closed by the
time I get home & not open on weekends so maybe Ill try the counter clockwise Co adjustment to lean it out. Do the Quantative dizzy check.
Today it ran pretty good on the way home dint have the off idle prob.
though there is a power loss at the top... some kind of fuel delivery prob.
I took out the plugs and put them back in as they were fine and replaced
the dizzy cap. Im thinkien its Co cause of the little backfires when you let off the gas.

That did it I made 3 adjustments of the co leanen it out
and by the 3rd time everthing cleared up I took it out for a run and itll run right up to 5 grand. Clean filter helped alot. Thats a good feeling.

Now Im off to a b-que at my friends hes leaven wed. to florida to make some money buttoning up damaged houses from the hurricane guess hell gone for 3 months he wanted me to go along though I cant.
