With no consistency my 2.0 fi car will sputter and shutter. Its hard to tell weather its a lack of fuel or a lack of spark. Its fairly speratic but constant once the car is warm. What I usually have to do is stomp it or feather it past 4k rpm and it runs fine above 4k.

Things ive fixed/replaced
New oil and filter
new fuel filter
Checked/replaced any bad vacuume hoses
replaced and calibrated the tps
checked mps
checked aar. Stays closed 24/7 which is better than open randomly
new cap
new rotor
Adjusted timing to the best of my ability (IMG:style_emoticons/default/blink.gif)

I've owned this car for over a month now and it has never run properly due to this problem. Today im going to check the injector points and do a valve adjustment. I can hear the injectors firing with the key in the on position but they could still have issues I suppose. Help me... carbs are calling my name.

I agree with these suggestions (dwell, timing, fuel pressure), but I'd also check the connection to the CHT. Could a bad connection to the CHT or a failing CHT cause symptoms such as this? If the ECU is getting inconsistent head temperature readings it's going to do funny things. If the engine is warm and you sporadically lose continuity with the CHT the ECU is going to sporadically make the mixture too rich.

Just another theory.
