My car is still being goofy. I replaced the MAF and now it is'nt throwing any codes but it still runs exactly the same. When its cold it surges and sputters and kicks back and forth like a rodeo bull. Then when it warms up it stops but does'nt seem to have any power at all. It barely chirps second!! It feels like its suffocating or something...Any suggestions?

Here is what has been replaced so far...

Cat-back exhaust
MAF sensor
plugs (ngk vpower)
wires
cap
airfilter
oil flush and change
fuel filter
ps/fan belt
lucas fuel system cleaner
and am running 93 octane

I have a suspicion that the ignition timing is off but I have no gun to check it with...
