Meaning, us people that use english to talk to each other have no clue what you are talking about. You used zero punctuation and as far as I know, you have a subaru, a slow throttle response mod, and you got your fuel pump from a cigarette maker. O.o

Stop, take a second to think about your problem, and type it in again.

Also use this if you have to.

We can't help you unless we know some details on the problem.

Your engine is running on 1 rotor.

Do you have a fuel cut defenser installed?

Lol, did you check the compression when you got the engine?

Is you timing set right?
Having the timing off enough will cause a slow throttle response, and make it run somewhat crappy.

Search for "timing", theres a pretty good recent thread about setting it.

If its a used motor that you dropped in and its only running on 1 rotor, it could mean A) You got fucked and one of the rotors is dead, or B) the seals are stuck from sitting/carbon.

There are plenty of different tricks to free seals that are stuck, but regardless, do a compression check (Shoulda been done BEFORE you paid for it!)

There could still be other problems that would make you engine run on 1 rotor, despite what Shainiac would have you believe. Running a N374 ECU for instance would cause it. Or perhaps a no-spark issue is at fault, bad wiring harness maybe?

A compression check is a great place to start but if the engine has compression then what?
