Please help people I'm stumped. so I have a 99 civic ex. I swapped a b18b out of a 99 integra I believe. I put it in the car ran hard for like a couple days then all of a sudden it started running like shittt. It was breaking up sputtering and carrying on wanting to shut off. It barely has any power. I just did new plugs new wires new dizzy new cap new rotor...what else could it be?? I did notice my speed sensor could be bad. I got **** in it when we did the swap I cleaned it out now it just stopped working..cleaned it again still don't work could that affect anything?? By the way I'm running a chipped p28. Like I said ran strong then all of a sudden it started running like ****. Please help people!

Could be a bad ECU, try a P75. Could be timing, gounds, it really could be alot of things.

First thing you need to do is check to see if you have any check engine codes being stored.

Do you have any codes?

Well I threw my stock ecu on real quick to see if it would do the same. I know it's vtec but it still should run right?? Check engine light is on but I'm pretty sure my speed sensors bad. Thanks for the title change ma dude

^^find out what the codes are first. also, are u blowing out any smoke? did u do timing correctly?

Would the timing just get all out of wack ?
