copy/paste?

theres a whole thread of things ive tried already.
basicly relaced


Plugs
cap rotor
fuel filter
TPS

had coolant temp sensor tested good still 02 is good still fuel pressure is good too.
When the car is warmed up at idle ill floor it it studders (like launch control) then the rpms go up.And if im driving in gear and i floor it it studders or wont go but if i slowly let out of it certain spots it starts to pull normal.

fuel pressure at 15psi is not good souldn't it be running some where around 40 or so PSI???

tbi is much lower pressure than tpi.
fuel pressure should be ok at 15
i would try an ignition module.

If it idles smooth Im going with ignition, couldnt
link to your post but like others said that 60hp
motor is happy with 12+ psi on a TBI.

Weak spark from old coil or pickup coil in dist. There
is an elaborate test for the pickup (I'v got a 2 minute
attention span so I cant read the whole thing) coil in
the dist but its a common failure. Spray the plug wires
with water, see if the thing miss'/dies. Pull the coil wire
and crank it, can you jump spark 1/4+inch's? If so do
the same with the plug wires, if its lower its in the
distributor pickup coil more than likely.

A wise man said "every vehicle should come with an LS1
regardless of make or model". Pitch the 2.5.
