sputtering problem

[ka24de89]

I have a 89 240 w/a ka24de swap. When the car warms up and i feed it gas it will starts to sputter. When i shut it off it will run fine but when i rev it up again the problem comes back.Already changed fuel filter and flow meter the problem still occurs. I was also wondering if these car have some sort of cam sensor and if they are hard to replace

check your timing, and your tps. Also, check for vacc leaks. Might as well check you coolant temp sensor. Could be a number of things.
