Hi guys, new to the forum wondered if anyone could help back in feb I got a rs265 and since then every now and again it would hesitate throughout the gears. Sometimes when I’d plant my foot it wouldn’t be getting full boost (would stay at around 0.45 bar) and literally would take ages to reach high revs. It’s not throwing any codes up so that doesn’t help I have done: plugs (gapped to 0.75) Fuel filter Air filter Always run on shell/shell v power Recirc valve Boost Pressure test and held Pressure Any suggestions would be perfect, thanks guys
Plug gap at 0.75 seems big. I was recommended by my tuner to gap them to 0.5 and my hesitation was cured Sent from my SM-G975F using Tapatalk
0.5 really?! Even at stage 1 I’ve been told .6 is the soft spot. Might go down to .7 though if there’s the slightest chance for it to work
Gapped them earlier and haven’t noticed anything for time being however lowest I could go was .64 depending on how fussy it is, will have to get the right size tool. Thanks guys for the fast replies really appreciate it!
One of my coils had a load of brown sut on but surly if it was a coil It wouldn’t be every now and again? Will check sensor though
They are really finicky things, you would think it would show up on idle or at high rpm's but it all depends on what is starting to break down with them.
usual suspects are, coils, plugs (0.6 gap) injectors and thermostat, if its not had stat change i'd do that as matter course anyway
Didn't think we had a crankshaft sensor. Maybe that was just mk2s though? Where is it located? Edit: was thinking about camsensor while writing cranksensor. My mind is too complex even for me to understand sometimes..
Yep they are! It stops at 5.5k then runs mint or if I let off then apply throttle again. Ive put some RPD oem plugs in, meganes aren’t funny with what type of plug are in I’m hoping
Coils are next to be ordered along with thermostat. Tried treating injectors with a bottle of red-X over time but still nothing. Maybe I need to test them out the car if it comes to it
how many miles has the car done, mines on 114k and still had the original injectors, if you think it could be them then either replace or ultra sonic clean them. Where is the temp gauge needle pointing ????
just past 51k miles. Yeah I could change them but would it be batter to spend the extra bit for bigger ones before I map it? My temp gauge sits just over halfway and has never moved past
If you get 630 injectors, you can't fit them before mapping, it will run way too rich. That's the right place for the engine temperature where the needle is, so no need to replace the thermostat.
yeah I’d have to get it done on the day of mapping but if it’s not the problem then I don’t want to waste a dyno day lol
Just realized my 250 sort of does this if i cruise at around 50km/h in third for like 15-30 secs and plant my foot. Something with the original software i think. I remember reading there was a software update that fixed what i think was this issue. I get around it mostly by not cruising Does it only happen i third or is it every gear?
move had it happen to me from 2nd gear all the way up to 5th. Yeah literally only when I plant my foot it kicks up a fuss
