reving problem

[wickidillusion]

All right i have swaped a i motor in my eta it runs great, but when im pushing down the throttle just a little bit it will climb in rpm's any higher the motor cuts out. and then when i floor the pedal the car only 4000 rpm and then acts like there is a rev limiter there.

what do you think it would be?

fuel pump.

crank sensor

if it rews up well and at higher revs it has problems first of all check the fuel pump... u may install the 3.5 engine pump, it lasts longer and pumps more fuel :)

My car has a brand new pump (its an m10) and it hits what seems to be a rev limiter @ 4500rpm... could my tack be off?
