Hey guys i just recently had an 01 b18c1 dropped into my 96 GSR. As soon as i got it back i have an engine code of misfire in the 3rd and 4th cylinder. This engine is brand spankin new, 30k miles so i know it isnt the engine. I know 2001 was obd-2b and my 96 was obd-2a. It idles a little rough, runs fine in upper RPMS, and hits VTEC perfectly. Now i have to be at work at 5, so should i be running my car like this, am I going to f**k anything up. My last motor has a brand spankin new 96 distributor on it, i was planning on swapping those.
