what is wrong with my car

[Baron96JDM]

i put a new engine in my car 2 weeks ago and put the same one used from japan. but tonight when i was toppin it out it cut off at 95 mph. then i took off in1 first gear it red lined at about 5700 rpms and started reving up by itself. does anyone know if this is my compter or trans or something else

[Chris]

clutch? were you hitting the gas when it reved itself?

[Gooback]

wouldnt be the trans proly the ecu did you use the saem one as before or a new one? also jdm ecus top out at like 112 or so too, aslo it would help others to know what motor what obd and what ecu you are using

[Baron96JDM]

i had a d16y8 but i blow it up, so i got a d16y8 from japan. we used the same ecu and my last would top out at 120.

Did you do the timing on your engine? When I first put my D16Y7 in my CRX I didnt time it and it would only go to like 5800 intsead of 7000. check your timing.:angel2:

[Baron96JDM]

how did you go about doing that

[CRX boy]

Get an opened end 12mm wrench and loosen the three bolts on your ignighter, then you push it towards the back of the car to advance the timing or pull it towards the front to retard it. But in your case it sounds like it needs to be advanced. do not remove the bolts completley just loosen them. You will need a timing gun, in my case I didnt have one, so I just listened to the motor until it sounded like it was idling right and then rev it up and see if it hits redline like its supposed to! then take it for a test drive! your motor should redline at 7200 RPM. dont forget to tighten the bolts back up when you are done, do this while the car is running.

Oh yeah you said the car was revving up by itself, make sure your throttle positioning sensor is plugged in and you have all your vacumm hoses plugged in properly. Or your throttle positioning sensor could be going out. It is very common for that to happen to Honda's especially if you have an intake.:angel2:

[Baron96JDM]

thanks i will try that

[CRX boy]

Did you fix it yet?

[CRX boy]

During your swap did you pull the intake manifold off that motor? if so did you replace the intake manifold gasket, if you pulled it off and did not replace the gasket I am quite sure that you are having a major vacumm leak.The same goes for removing the throttle body
