just put an f22b from a 95 accord in my friends 90 accord and used old engine harness.. the ca runs and idles weird and it wont go over 2,000 rpms.. does anyone have any idea wat can cause this... we switched the ecu's but that did not help

 

Did you start the other engine before installing it, or was it already pulled??

 

is it the dohc f22b?

 

no the motor was already pulled... and its a single cam...i thinkk it has somethin do with the distributor but all the plugs are just fine... and i dont kno wat can cause it to have a rev limit

 

^^

 

are either of the engines vtec and are the connections ok?

 

well the only thing to my knowledge that will cause a rev limiter is the ecu...either it is in limp mode or there is a bad connection

 

The f22 that we put in is vtec and the ecu for the engine came with it... we tried 3 different ecu's and all had the same issue...could a sensor possibly cause this?

 

Out of those three ECU's have you tried to retrieve any Diagnostic Trouble Codes? See if maybe a fault somewhere in the PGM-FI system might be causing the problem?

 

So how exactly did you manage to plug an OBD-1 VTEC ECU into a pre-OBD wiring harness?

 

90-96 accords are obd1 f22's

 

anyways, check if you have any CEL's. check your grounds. make sure your MAP or TPS sensors are swapped.

 

Um, no. Are you dense?

'92-95 Accords are OBD-1. '90-91 is pre-OBD and '96+ is OBD-2. VTEC is '94+ only.

So explain to me how this guy plugged his '90 Accord engine harness into a '95 Accord VTEC ECU.
