Excellent advice! I always try to reset the ECU after any modifications. It helps clear old error codes and ensures a fresh start.
I’ve read about issues with engine performance if the fouler isn’t the right size. Can anyone recommend specific brands or models?
That’s true! You might want to look into the Denso or Walker fouler options. They seem to fit well for many setups.
Humor me, but what if instead of a spark plug fouler, I just put a sticker on my O2 sensor that says ‘You’re doing great!’? Would that work too? 
Haha! If only positive reinforcement worked that way! But on a serious note, spark plug foulers are a more reliable option.

Reflecting on all this, it’s clear that while spark plug foulers can offer a temporary fix, identifying the root of the O2 sensor problem is key to a long-term solution. Always best to research thoroughly!
I recently installed spark plug foulers to resolve my O2 sensor issues, and while it helped initially, I started seeing a check engine light. Any idea what might be going on?
It’s common for that to happen, especially if the engine isn’t running optimally. Have you checked for any other codes that might indicate a different issue?
I agree with Christopher. Sometimes the installation can mask other underlying problems. A thorough diagnostics check may reveal additional issues.
I had a similar experience where installing foulers improved performance at first but began affecting fuel efficiency later. I’m curious if anyone has seen long-term benefits?
After putting in spark plug foulers, I mean who wouldn’t expect a little chaos? My car was like, ‘Thanks for trying, but no!’
Maintaining that setup can be tricky. Regularly cleaning the sensors and plugs can help keep the setup functioning smoothly.
Great tip, Diana! I learned the hard way—neglecting maintenance that seemed trivial cost me in the long run.
Has anyone experienced any improvement in response times after installing foulers? My car seems a bit sluggish now.

You’re not alone, Rebecca! My car was feeling sluggish until I got a proper tune-up after installing them.
It’s important to monitor your fuel efficiency closely. If you notice a dip, it might be time to reassess the entire setup.
Honestly, I think spark plug foulers can be a bit hit or miss. They’re not a guaranteed fix for O2 sensor issues, but worth a shot with other maintenance.
True! Sometimes I feel like we’re all just playing a game of mechanic roulette! Good luck to everyone trying these solutions!
