Unstable Idle or Throttle Response
Is your Jeep acting a bit too rebellious after the TPS reset, with its idle resembling a caffeine-deprived squirrel? Here’s how you can rein it in:
- Inspect for air leaks: Leaky hoses or intake gaskets can wreak havoc on your Jeep’s idle. Give them a once-over to rule out any sneaky leaks.
- Clean the throttle body: Gunk and grime can accumulate in the throttle body, causing erratic throttle response. A good ol’ cleaning session might be just what the doctor ordered.
- Perform a throttle relearn procedure: Sometimes, your Jeep just needs a little reminder of how to behave. A throttle relearn procedure can help recalibrate its manners.
Keep calm and Jeep on, my friends! Troubleshooting these common post-reset issues is all part of the adventure.
