ok i put in a new f22a motor longblock in my 92' accord and i used all the old external parts(intake,exhaust etc...) this did not happen on my old motor. what happens is when i start the car. its like someone has the gas pedal to the floor. it just revs right up. when it hits 4500 rpms i just turn it off because i dot want it to redline. any ideas.? and its not giving a CEL.

Thanks

 

look at your throttle body to see if it's stuck open???

 

nope its closed

 

Vacuum leak.A piece of the old intake gasket under the new gasket.

 

thats what i thought. cuz i checked all the lines and what not and they are fine. but when i did put new gaskets on the plenium and the one onto the block there was some crap left on the gaskets. wow that would cause that much of a vac. leak? crazy...

I've seen it happen before.

 

kool man thanks, i'll check it out tomarrow after work and let you know if it fixed the problem.

 

gasket didnt fix the problem. i found a crack in a vac line. fixed it but didnt solve the wot problem. this is really annoying. is there a way to find out if theres a leak by ot running the motor?
