Hey Scotty,

I have a 1996 ford f150 v8 5.0 that shudder on me when ever I put a load on it like going up a hill changed out plugs and wires new throttle body new tps and air mass flow sensor were replaced and still have the shudder feels like going over a unpaved road now I have a code po411 Secondary Air Injection System Incorrect Flow Detected

often transmissons start to wear internally and do just that on those Have a pro check that first

I had that done when I had the torque converter changed it does it between 25 to 45 mph then its gone code po411 Secondary Air Injection System Incorrect Flow Detected is coming up know would that have something to do with it and if it does what and where is it
