I am new to tuning and I have an 04 Silverado with a 5.3 it has a tr224 cam long tubes offroad y pipe into a single 3" magnaflow race muffler K&N cold air intake and has been running real good till last week. I left work and it was raining really hard my drive home is 28 miles from work about 8 miles into my drive the torque converter unlocked (3200 rpm circle d stall) but I did not notice any loss in power but it was raining the converter never did go into lock up when I got off the hwy I did notice that it was missing a little and popping out the exhaust under acceleration got home and hooked up HPtuners and looked at everything I had the p0101
I cleared the code and started the truck and with in a few minutes the CL came on with the same code p0101 so the next day I took the maf sensor off and cleaned it very careful not to damage the elements checked all the wiring to the maf sensor all seems ok checked for air leaks at the map sensor and intake manifold all is good reinstalled the maf sensor after it had dried for a hour or so started the truck and after a few minutes the CL came on and guess what p0101 was back so I figured with all the rain maybe the maf sensor got wet and it was bad I bought a new one and installed it cleared the code started the truck still has the same miss and does not rev smooth and fast as it did prior to the issue and the p0101 code is back. I am not sure what it is I don't want to damage the motor and drive it much but I did log a little drive and the maf sensor is reading like it has in a previous log I am lost my stft are all over the place and the truck is running rich I pulled the plugs ngk tr55 and they looked ok but changed them anyway any ideas here is my last log maf scan.hpl
