Excellent product and flawless service
Had a problem with my Ford C-max. Irregular idling revs. Very sluggish uptake if you slowed in second gear and then tried to accelerate again in same gear (which you do all the time in London!). Also issues with it spluttering and stalling at junctions and when reversing into parking spots.This product did exactly what I hoped it would do. Sprayed it into the throttle valve and I wiped away the deposits I could see. Image 1 is before, image 2 is after obviously. Gave it a good spray inside the throttle body too to be sure.Here’s a tip, don’t push the valve open manually if it’s electronically operated as that has the potential to damage. Instead turn the ignition to power on (don’t start the engine), then brace the accelerator pedal hard down inside the car to open the valve.The engine will be a bit rough immediately after treatment. I had revs spiking erratically and lots of spluttering. I thought I’d messed up, but it just needed a short run to settle everything down.Back to the product. It’s great stuff! Having used it it’s like driving a different car!!!Seller was great too, despatched promptly, no issues!

Great Product
This product does what it suppose to. I recommend getting two or more depending on what you need it for.I got one to clean a throttle body and by the end of it the bottle was finished.

Clean intake valve
Cleaned the intake valve very well. I was surprised how much dirt and oil was actually removed. Is a much better car now

Have you got an endoscope?
Used it. May have worked, but unless you strip off the entire induction manifold to inspect the back of the inlet valves, it's difficult to say. I suppose if you had one of those newer cost effective endoscopes, you might be able to do a before and after on the back of the inlet valves. There seems to be a fair bit of positive reviews on the ' net.

Does what it says on the tin.
Literally does what it says on the tin. It cleans the intake. Nice long straw included. A little bit pricey though. Can probably get it cheaper from the local motor factors.
