94 civic ex with d15 block and jdm 1.6 vtec head

Driving on 275 and was in 4th gear and about 4.5k rpm and it started to bogg and will not go over 5k rpm. Stoped at the store and checked my oil (oil is fine) So get home and check the dizzy and all wires everything checks out ok. Also when i start the car up it goes over 5k then about two mins of running it wont go over 5k again. So what could be doing this.


any help would be greatfull

 

ttt any one ?

 

I'll add somemore about what its doing. Once he gets it to about 4.5k rev It starts jumping around real bad, Almost like a funky cracked out rev limiter, But it also sounds like its misfiring while its doing this.

 

Could Be Running Lean!

 

going to work on it some tonight

check the dizzy and all the wires and stuff all looks good
could it be the ecu? or the vtec not working right? I was running the car for a few days with no vtec working. thanks

 

hook up the vtec/oilpress.. 2 the ecu
check engine lights ?
also check the rotor...

 

ok the vtec and oilpress are hooked up
have diffents ecu codes 7, 14, 21, 22, 41

what about the rotor?
