OBD question

[regalman]

I have the 94 regal with the 3800 VIN L motor. I read on the net that it might be OBD2 instead of 1.
It has the upstream and downstream O2 sensors, it has a MAF but I do not think it has a MAP. Does anyone know what version it is OBD1, 1.5 or 2?

OBD II had not come out by 94 so it can't be that

^^Correct^^ The 3800 Series 1's were never produced along with OBDII as far as I know. I'm going to say I'm 75% sure you're OBD1, but really there's no real difference between 1 and 1.5 besides a couple extra sensors and engine codes.
