Questions & Answers

What do you do with this product? Do you put it What's the location? I was wondering if you just had to remove the power for the sensor, or if I had to remove the sensor entirely?

The instructions are on the can and you just have to follow them exactly Fill your gas tank directly with it. As I was waiting for a catalytic converter that was on back order over a month, that stuff saved me a lot of time and frustration! It would be a good idea for you to purchase an inexpensive funnel...

You have some good stuff here

5/5

Anyway, after I got that stupid P0420 error code, I bought this. My expectations weren't great, but I was pleased with the improvements I saw. The post-cat temperature was low for quite some time as I had been running the car with a defective post-cat O2 sensor. I ran some before and after comparisons with my obd2 scanner, and I was amazed at the difference between the temperatures. I'm still going to have to replace the catalytic converter, but this product gave me a little wiggle room.

I've had great success with it! It has now been 8 months since I've received my catalytic converter! There was no way I could stand to have my engine light always The tank has one can and you need to fill it with water Light has gone out on the engine!

I don't want your trouble! This is not the first lqm product I have tried, but I'm not satisfied with this one either

3/5

LqM should first design the product together with the spray unit rather than waiting for the customer to figure out where to get it. Before using this product, I was using Jectron injection cleaners and the car runs smooth and perfect. I can feel no lag when I apply However, after using this catalytic cleaner, the power lag comes back, until I flush the power line with the lqm. The model year is 2010 and I have a 102 horsepower Audi Q5. The following is a sample of 1000.

It's fantastic

5/5

I love it. Immediately before applying the product, I noticed that the vehicle began to oscillate when it was disconnected from the mass air sensor When I start to apply it, the abnormal revs resolve on their own before I finish the bottle. What is amazing is how quickly you can feel the difference, it is like having Liqui Molly, I'll get it done.

The Landrover LR3 is not compatible with this plugin

3/5

Despite the fact that Liqui Moly is not to blame, the cars below 4000 RPM will just stall when you disconnect the MAF. Thus, it is almost impossible for an applicant to apply since he is required to apply by 2 Three thousand revolutions per minute. In the event that this could be made MAF-safe, it could be made suitable for Land Rover.

Germany is the manufacturer of this item

5/5

Exceptional quality as it is made in Germany and cannot be compared to anything you can find at Advance AutoPart or AutoZone.
We measured the catalysis temperature before and after cleaning, and it was clear that it had been really cleaned.
