Since I purchased SX HFC I've been having problems with the check engine light being on. No matter what I tried it wouldn't stay off. The CEL fix that I had was basically a spacer for the O2 sensor which still gave me the light. Fast forward to today, I received my TF CEL fix and installed it. Installation took all of 10 minutes which included bring the tools out and putting them back in. I went to the bank which is maybe a 10 minute drive. On my way back I noticed that the CEL was gone. I've pushed the car and drove it at a steady speed to see if it'll come back on but it hasn't. I know a lot of people are having issues with the CEL light staying on and problems with how far spacer is putting the O2 sensor away from the exhaust flow. Many have it either too close or too far which would cause a CEL. These guys seem to have the perfect setup for it.

 

Yep, the L CEL fix adaptors are good.

 

Guaranteed to work or your money back. I have that on my TP too and it works right off the bat.

 

I throw a p0139 (O2 Slow Response) with the TF cel fix... on the MXP TP. Running two antifoulers worked best for me.

 

Clipse,

What were the exact anti-foulers you used so I can pick them up at an Autozone? Is there a certain thread size I should look for? I have the MXP TP too and my CEL comes back on and goes away every now and then.

Thanks!
