when i get to 4700 rpms my car starts to kind of hesitate i changed the fuel pump and fuel filter but it still does it.could it be my distributor rotor my friend to change it soon.the engine i had before started to do it just before it went out it was a 2.3l vetec sohc. the only parts i put on the new engine was the cap rotor,and the egr.and the map sensor. yes its an acclude.and i have msd ignition box,and my tach's hooked up to it and when it hits 4700 rpms it shoots up to 11000 ya the shits wierd but my vtec controller says the rpms im exactly going!help me out guys i really need it????????????????????????????

 

maybe the MSD box is messed up

 

i have the same set up as you.i had a similar problem, it could be the wiring of the msd. thats what it was for me. like when you go and it gets around 4200 to 4500 it kinda like staws a bit or some sorts. well anyway check the wiringof msd.

 

ya!around that rpm it does it.should put it back to stock and see what happens?well what did you do did you rewire everthing on the msd.

 

heres the scoop that was happening with me. like i said before i have pretty much the same set up. when i hit those rpms the car would stutter. only when cold though. another problem i was having was when the car was cold it would not crank up. the motor would turn but nothing. i took to my mechanic and he said it was the msd wiring. i was like nahhhh cant be. anyway i left the car with him and when i returned to get it it was cranking fine and rev up fine. i asked him what was done and he said he put the old coil back. told me to bring the car back in a couple days when he has time so he could set the msd set up correctlty. but yeah he said when he took the msd ignition cap off (the part where the spark plug wires connect) that it was all smoked out. so all in all the connection was ghetto rigged. that was my problem.

 

not a coil i mean the distributer cap. thats it. you should check it see if it is smoke dust around n black. you ever have any problems cranking it up?

 

well when i put gas everytime, when i go to start the car the takes a while to crank like if no gas get to the engine.i changed my fuel pump and my fuel filter.so i know its not that.i think it my injectors?what do you think!

 

thats exactly what was happening to me. the thing is its going to get worse and worse starting the car. like i said check your msd distributer wiring.you could put the old one back to see if the problem continues. then you'll know for sure. its pretty simple.

 

i bet its that but if its not you have to start with the basics. get the battery -starter-alternater checked. check your relays, battery terminals, stuff like that.

 

peep this when i take off the msd it wont crank over but when i put it back on the car fires up right away
