My truck is running rough and I have done what I have seen on here as to keep in running and unplug the sensors one at a time to see which one is malfunctioning, well I think it might my TPS sensor because I disconnected it and it made no difference and the sensor directly before that one to made no difference. I want to get better mpg and it idles rough so this is what I think the problem is. I have already cleaned the MAF and checked it too it's fine. Any input would be greatly appreciated. Thanks
