After I cleaned the throttle body on our 2007 Jeep Wrangler JK I started getting the Lightning Bolt Symbol so I am doing a Throttle Body Relearn.

Watching this video brought back memories of a stressful time. I had a high mileage Toyota that started to idle too low. No codes. I had never cleaned the throttle body, so I did using throttle body cleaner, an old toothbrush, and a rag. After I finished I immediately got a code for throttle body performance on my D8BT. I pulled it apart again with the sinking feeling that I just did something to destroy a working throttle body. It turned out there was a single thread from the rag I used that was caught between the valve and the throttle body wall near the pivot. That is all it took to get a check engine light.

I had to replace throttle body, gas pedal. That made that light come on occasionally. Finally fixed it by replacing the air intake temp sensor. I have 491 k miles on those parts.

I'm having this same issue, but unfortunately mine is worse. It's on a 2010 Dodge Nitro. 3.7L .. I'm getting the lightning bolt on the dash, but NO codes; and it will go into limp mode. But if I just cycle the key, it all resets and goes away again. So I cleaned the throttle body to make sure-- it was quite clean, being that it's only a couple years old since the last one broke some internal gears... So I was thinking it's the accelerator pedal then. As you know, there are two potentiometers inside the accel pedal.. So I graphed them both: APP 2 is having a pulsing drop out every 3 or 4 seconds. sometimes 7 to 10 seconds.. but usually shorter intervals. It just drops out over and over.. Whether my pedal is half throttle or held to the floor, or even untouched -- I can see it drop out in every position......... So I disconnected and tossed the accel pedal aside completely: and shorted my accel wires to the signal wire (through a test light) at the connector, down at the pedal--- so that it raises on the scan tool- simulating holding full throttle: just the same as it does when I step on the pedal in normal use. and APP 2 STILL drops out in random pulses?? Even after bypassing the accel pedal completely..
