FRP emmisions seem to getting worse YOY at the MOT - getting borderline now

I'm a heavy FRP user - 100 miles a day - currently @ 85K miles

Reckon these 2 might help

- STP fuel injection cleaner
- STP multi-valve cleaner



Anybody got opinions on these?

I've used the WYNNs injection cleaner a couple of times in the past with no problems

Just a little cautious about the multi-valve cleaner given the Puma's Nicksil lining...

Not really convinced, why? Engines are good today; fuel (normally ) is good from the mainstreams, air in UK is clean; so not convinced they are required. In terms of emissions; FRPs need to be red hot just prior to emissions test, so you know what to do on your way to the garage Anyway, it won't matter soon as MOTs are going to be only once every ten years or something ....

dont know about them products mate as everyone seems scared of them??

only one way to find out

i was told 2 years ago that wth the new laws racing pumas in another years time will hardly ever pass the mot as the sport cat really does hardly do anything.

perhaps your sports cat needs replacing that might help it a bit but a expensive option i know

my last mot i took the car for a hard half hours drive and then it was standing with engine on for half hour and then it still took them about 10 minutes to get it through the test neally didnt pass.

need to find me a dodgy garage this year i think.

i found this..


Engine emission control.

The 1.7 Zetec-S VCT engine is fitted with a positive crankcase ventilation system. The system consists of a valve mounted into a separator (attached to the cylinder block) and two hoses. One hose connects the valve to the intake manifold. The second hose connects the cam cover to the air cleaner

Under idle and part throttle conditions, crankcase vapor flows into the intake manifold where the vapor is burnt during combustion. Under full throttle conditions, the vapor flows into the air cleaner via the cam cover. During this condition there is no fresh air circulation from the air cleaner to the cam cover.

Positive Crankcase Ventilation (PCV) Valve?? i wonder if this can become faulty meaning it wont sort out emission control properly??


just a thought.

Well, I've had a new mid section (ie new cat), new manifold and a new hego sensor fitted within the last 2 years

One option I've been told about is putting the FRP through a Ford computer diagnostic (take a whole day)

hego senors dont seem to last long on the frp, ive heard of some going within a few months and they arent cheap are they.

whats that ford thing involve then????

Most of these additives contain octane booster...so your car will obviously seem improved when it's added but it is a bit of a trick.

Increase your chances of passing emissions by having a clean air filter, plugs, clean PCV filter (usually a small foam block found in the air cleaner box) and a RED HOT cat when it goes for the emissions test. i.e. the car needs to be driven hard prior to the test.

It's rare for a (metal) sports cat to fail as it's much more robust than the ceramic one found in all other cars. It's more likely the lambda sensor (another part of the emissions kit that feeds oxygen levels back to the ECU) to fail...this is the part that dies if you've been a victim of the latest silicone in supermarket fuels problem.

It was driven on a motorway for 25 mins beforehand - got there for 2pm - wasn't tested until 5.15 (heard a lot of revving in the back around this time)

There seems to be an issue with CO emmisions on fast idle and second fast tidle tests

Vas - what do you do before you take it into Mansfield?

I have used these type of additives before, though not on a Zetec 1.7.

It is my personal belief that a good dose of injection/fuel line cleaner above that found in Petrol could probably do some good.

I remember a story about a guy (mechanic) taking an engine apart once and being amazed at the lack of gunk/varnish/build-up. He said it looked like new. The owner of this engine claimed to have used an additive twice a year for 8 years or so. Might be a link.....

It's tough to call. Sometimes deliberately cleaning things can cause unwanted particles to get in your system. A good example of this is engine flush. If your car hasn't had it before and you flush it out with a powerful product, it can lead to disaster.

Injection cleaner is probably pretty harmless on an already clean system.

Going for a full days computer diagnostic @ Ford Mansfield on Thursday - got to get there for 8.30am!!! - cost is £65+vat

I'm assuming they'll update the firmware (last time it was briefly checked I didn't want it upgrading - nothing was wrong with the car - why mess?)

I'll let you know...

that was a waste of fuel I drive mine hard for 30 minutes it is booked for a set time it is tested within minutes of arriving at set time.
