I ahve developed an engine proublem. Driving at Highway speeds 65+,
while eccelortating. At times my engine loads up, as if the cat is
plugged, Mods done are- K&N air filt. direct fit headers, high flow
cat,high flow muffler, Supper chip. new quality dist.cap roter MSD plug
wires Bosh platinum plugs and High output coil. I'v had this proublem
before the ign. tune up and the exhoust mods.
I can't think of a cure.
Suggestions please.

Check MAP sensor and mabye TPS too but you may have problems anyway with
all the mods on it. Closed loop engine do not take to kindly to low
restrictoin exhaust sometimes and it might no be heating up the O2
sensor correctly and causing a over rich and also check thermostat and
make sure it is atleast a 180 as a colder engine can cause it to
overrich too.
