OK just swapped a B16A into a 98 dx coupe. Everything was wired according to diagrams i got from the forum. It starts and idles fine but seems to be in limp mode only revs to like 3400 rpm and hits a rev limiter????
Anyone know what sensors can cause this so I can check the wiring again for problems or maybe get new sensor if needed.
Any help would be greatly appreciated.
thanks
 
Is there the proper ECU in the car for the engine? If it is an automatic ecu it will do that. Other issues can cause this as well, but you need to scan it and see what codes are being thrown.
 
check to see if you mixed up the plugs for the map and tps. Both are three pin connectors so its easy to do so. Mixing the connectors will also cause the symptoms you describe, because the ecu sees similar voltages from both sensors at idle, the car will idle fine. When you try to rev it up thats a different story.
