My car was originally a 95 Integra S.E. I got a 97 B18CR motor. The car is originally an OB1, however the ecu is an OBD2, so i had to get a jumper harness. Before dropping it in, me and my freind bolted on a JRSC w/boost upgrade kit.
Now, the car does start, however idles around 1k rpm, and seems to be missfiring, idles kinda rough. The engine check light came on, so my freind checked for codes. Said codes for the 2nd O2 sensor(dont have it), TPS, MAP, and CKP or somn was showing. We tried a OB1 ecu(p30) to see maybe if something was wrong w/the jumperharness, however found no luck. I did find that the TPS and MAP were switched around, so switched em around. Still no luck. So, were now stuck...dont know where to look or wut to look for. There are a few things that I wanted to mention...
-The JRSC w/boost upgrade kit did come with a BTC(boost timing controller), but we have yet to install this.
-Kit came with a fuel pump...have not installed this either.
-On the passenger side by the battery, where the main engine harness connects too, there are 4 plugs, but only 3 are plugged in. Are there supose to be 4 or 3? Dont know where the 4th one which has 6 cavities or wires goes too.

As you can tell, in a situation..where I am totally confused and lost, and dont even know what to do any more. If anyone could help...pleaaaaaaaaaase!!! Cars been in shop for lil over a year now...wanna drive the damn thing!!!!!!
Thank you.
