So today i had some downtime and decided to clean my viper throttle body and k&n cold air intake cone filter. I purchased everything necressary to properly clean both the filter and the TB.

When i reinstalled everything, the engine violently shook. The CAI sounded like it was sucking in way too much air, the exhaust sputtered and the jeep shook violently. I let it run for a minute but had to shut it off in fear of something worse happening. . I turned it on and off a couple times and finally after letting it sit for about 30 seconds, it began to run normal. I took it for a ride around the block and after i floored it once, the dash lit up and I wasn't able to accelerate.

Does anyone have any suggestions or ideas on what could have possibly happened?

Thanks in advance

 

Did you oil up your air filter element after you cleaned it ? I assume you did if it's a K&N. If the filter has been over oiled it can suck the access oil into your intake sensors and mess up the readings. They sell specialized cleaner for sensors at most auto stores if you think this might be the case. Another thing to check would be any sensors with loose connections. Might even disconnect the battery and let the computer reset everything and then start it back up and let it idle for a while learning the new airflow characteristics. This would be the last step if you checked everything else first.

 

Sounds like the Jeep is in limp mode. I assume you uninstalled the TB to clean it and you didn't do it on the Jeep. Did you damage the TB sensors?

 

Wouldn't that be more for a vehicle with a MAF sensor? JKs don't have a MAF sensor.

 

Im not really sure. Everything clicked out and in ok. Disconnected the battery but no luck on resetting the system. A buddy of mine mentioned that it is probably the mass air sensor.

Any thoughts?

 

Got these codes after plugging in my flashcal. I appologize for the sideways pics. My lg g3 does that sometimes

 

I've seen similar codes fixed by unplugging the throttle body connector, spraying some cleaner on the pins and sockets, and reconnecting the plug.

BTW, the JK has no mass air flow sensor.

 

thanks for all the help. I missed a post before that mentioned over oiling the filter. i think its possible that i did oil it too much. Would i need a new air sensor or any other sensor?

 

Any modern fuel injected engine with intake sensors can have this problem.

 

turns out ronjenx was right about that connector. unplugged it, plugged it back in, cleared my codes and re read and everything is working great now!

thanks for all the help!
