Spark plug hot or cold?

[Kimbo641]

Hello. I’m wondering if anybody can give me some insight on wether I’m in need of changing my spark plugs (hotter or colder)
I drive a Mercedes CLA 180 sport, 1.6 petrol. I’ve had the car remapped stage 1 (incl pops and bangs ) and also had it straight piped and decat followed with a lambert map.
I’m unsure wether my spark plugs are right for this kind of setting so if anyone can shed some light on what to do I’d appreciate that.
Another bit of information: between the range of 2000RPM - 3000RPM, if I hold my throttle at a certain spot anywhere between this range - no matter what gear - I feel a misfire. This will continue to happen as long as I’m holding the pedal in the exact same spot until I either press more down on the pedal or slightly release it. Is this caused by the plugs?
I’ve had servicing done etc and can’t find any other issues it could possibly be.
Thanks in advance

So you are experiencing pre detonation ?

If so yes go 1 grade colder spark plugs .

Hopefully you have informed your insurance company of the modifications? Be aware that MOT inspectors are now looking for evidence of catalyst removal and will fail a vehicle where this has been carried out.

Go 2 grades hotter. The sooner that piece of trash blows up the better.

Harsh!

If insulting strangers online is how you spend your time, maybe it’s time to go 'two grades higher' in maturity.

All modifications are above board with my insurance thankfully. Of course except for the decat for its reasons

You can help not choosing to add to the pollution burden just to get your "pops and bangs" and gaining little in performance.

Rub it with candle wax and then really rub it. Like really rub it. That'll get the chute all slidy again. Wait until the rain's stopped though - and don't let your little sister steal your bike again. You know how upset you get when she does that.

Help? I help by paying my car tax all whilst I don’t see the benefits coming back. You want to be a sheep and live your life following all the rules set out for you then that’s your choice. Wont get too far in life pal

As a second car, I can do what in the world I feel like doing to it. Legal or illegal, and ain’t you or nobody able to stop that from happening be a bum and follow your society’s ‘rules’

There are different forums on the Internet for different things. This particular forum just isn't the right place for seeking advice for these types of modifications. There are plenty of other places to post these particular questions online. Good luck.

How do you know how far I have managed to get? If only you knew! Just for your information it's far farther than you ever will I can can bet.

I'm not the one trying to get a performance boost from a 1.6 engine and I am not the little boy trying to act like a man and boost his ego with his pops and bangs.

You think that you are some sort of rebel striking out for freedom do you? Your arrogance is only matched by your ignorance (and your broken popping and farting car)

Another first order keyboard warrior to add to the ignore list! Tap away, at least I won't see any more of your juvenile drivel

Pathetic response and trying to justify it is laughable!

Rules apply to you too pal... like it or not. Especially the ones that say you have voided your insurance and if you damage someone's car or worst still injure someone your insurance company will put I cross on the appropriate box for undisclosed or illegal mods and not pay out and you could be paying that off for the rest of your life. In case you have not realised pop and crackle maps made ANY car sound white....and you might as well put a sign on your car saying "stop ME officer"! And before your say it.... I've never owned a car that was not modded to greater or lesser degree.... and I've owned a LOT of cars!
Definitely one for the ignore list...bye!

I listen to the infantile "poppers and bangers" driving round the city centre wrecking their engines.
I just think .... "GROW UP" !

Rebel without a clue. Who radicalised you? Who brainwashed you into believing being a member of a smaller flock is in some way superior?
