I am in need of some help. I recently swapped the engine in my 98 ka24 altima with a from a 00 ka24 atlima. Since it was completeled, it has been showing codes P1105 (map sensor) and P0304 (cylinder 4 misfire). I have replaced the map sensor with a used one from the junk yard, put new plugs, wires and distributor but nothing is helping in getting codes cleared out (even if I clear the codes they just come back). Another problem is that the motor bogs down when I give gas but around 2500-3000 rpm it evens out and runs smoothly (its kind of like a power band on dirt bikes). I am wondering if there is some sensors that are not compatible between the 2nd and 3rd gen altima that I am unaware of. Regardless I am stumped and hope some one can give me some ideas.

although I do not know about it , I can turn to our friend.until he tell me, I give you idea!
