I just finished my swap. I swapped in a 1995 b18b with a 1995 GSR tranny.

It started up great when I first fired it up. Now the problem is the next day I tried to start it up but it wouldn't start up. I check all the lines and all of that and everything was fine. I'm unsure of the vacuum lines though. Can someone give me a diagram of the LS swap into a 94 VX vacuum line? but yea i had a CEL on the tps and the map and the o2. ok after i swapped out the throttle body with a fresh one from my g3 and i resetted the ECU. I fired it up and it started. It idled up and down from 1500 to 1300 over and over again then shot up to 3000 thousand. Right when it did that I turned off the engine. Can someone please help me out. I really need this car running. I've spent 3 weeks working on it and still no go.

 

fix your cel

 

I've been trying to. I even swapped my throttle body from my integra with the MAP sensor too. and now it won't even rev up with the MAP sensor vacuum plugged in. When I have the MAP sensor plugged in it starts up then revs itself all the way to 3grand then just shuts off by it self. Can someone please help me out. I know it's not the throttle body cuz I swapped it outta my integra and i did a change over from my car's throttle body to my integra and my integra's to my civic's. So what else can be the problem?

 

Please i need help!!

 

Revving like that sounds like some sort of vaccum problem.

 

can someone help me please. If it's something as simple as repinning some plugs or what not I don't want to send it to the shop. Please anything will help

 

When you swapped throttle bodys did you use the same FITV?

 

I don't think my engine has an FITV... imma wake up tomorrow morning and get a fresh start and do some trouble shooting... anyone else has this problem? if so please reply anything will be greatly appreciated. thank you

 

I sorta had the same problem. I installed an LS throttle body onto my B16 manifold and kept the old TB gasket (B16). The holes of the gasket didn't line up and air was leaking from the bottom which caused my car to idle real bad. Replaced it with the correct LS gasket....problem solved!!!

 

I fixed the problem. It was my 240k mile fuel pump that was in. I swapped in walbro and now it runs fine.
