is this carb or fuel injected ?
will it bog down ?
do you know what the fuel pressure is reading when its bogging down ?
is it @ 3 to 6 ish ?
you need to add a T to the fuel line going into the car and drive it
if the fuel pressure is good and the compression in the engine is good then this issue is down to a plugged cat converter or a carb internal issue or the distributor itself being the issue
you T into the fuel line by adding a fuel line for a gauge to test with
when these bogg down its running out of fuel or the internal of the carb is causing this
make sure the compression is good in the engine also
does it still have a cat convertor on it ?
ok if no cat than its running out of fuel or the distributor or carb is bad
but check the compression first
see if that helps at all
but usually when they bogg down or choke out they are lacking fuel
how are you making out ?
if you have any questions please ask as i do not get credit for my work until you rate us here at Justanswer!
is the distributor in good shape internally ?
is the compression good in all 8 cylinders ?
