: 95 fleetwood codes

11-23-10, 08:34 PM
New to this forum. I have a 95 fleetwood that I just replaced the motor in. It runs really crappy so I ran the codes & got a 43 (knock sensors) & a 48 (MAF sensor). I replaced the MAF sensor, but it still runs crappy. Can anyone tell me what is generally the problem with these codes & how to fix them?
