91 Honda Accord help

91 Honda Accord EX
I recently put a 91 LX motor in my EX. Now i'm getting sensor erros. I still have the EX header on the car so the O2 sensor is in the rear. I have a LX and EX sensor. The EX sensor gives me a code 41, 43, 1 in the car. And the LX O2 sensor is giving me a code 1 only. The ECU in at this time is the EX I also have the LX ECU both are for a manual 5spd. OK well my problem is this then at between 1700-2000 RPM's i get a stutter from the engine. And also the codes 41, 43, 1 have come up. I desperately need to figure out what it is I need to fix.

Are you 100% positive all the grounds are connected?If the distributors are the same swap them and try again.The crank sensor is in the dist I think and I remember many problems with them.The dist usually clicked when it was bad.Did the problem start right after the swap?What are the differences in the 2 engines?

davo I thought the same thing with the Distributor at first so I out in one that had new parts and still the problem persist.The block is grounded properly, but to make sure I will re-install the ground strap kit I had on the previous engine. I have some of the body wires conected already just need to do engine point straps. The problem started after I put in some fuel system cleaner. But I have since then put in a new Fuel filter to rule that out as being the culprit.

Reconnect every wire before you go any further.Grounds are extremely important.You can fry parts by not having all the wires connected.
