1.8 t sputtering and struggling

[helix2]

hi, new to the 1.8t golf scene, i have a s reg with k03's turbo, walbro fuel pump, 440 injectors and a remap.

i have had a quick glance through the forum his my problems

bought the car 2 weeks ago now and got a blowing in the flexi bout a week ago now but its been fine to drive but today it was sputtering alot when accelerating and doesn't seem to shift as much as it did. it feels as if your driving a car thats just about to run out of fuel. would this relate to the blowing downpipe?

my other problem i have is my temp gauge, when the car is sat with the engine on it works fine and gets to 90 degrees as it should but when i start moving itll slowly start to drop back down to 0 degrees again untill i stop, would this be the temp sensor?

also when coming to a stop e.g traffic lights and i take it out of gear or put the clutch down the revs act as if youve just started the car up on a winters day. is this related to the temp sensor?

any help would be fab thanks!

new temp sensor an thermostat should sort your problem with temp droppin

For the spluttering problem, it might be a vacuum leak.

okay thanks, have already order temp sensor and thermostat as i thought thats what it would be.

okay thanks ill have a check tomorrow. would it have anything to do with the MAF or n75? im sorting exhaust out this week, if its nothing obvious at the moment would it be an idea to sort the exhaust out first may be down to 02 sensors?

It could be a vacuum leak, look at the hoses and hear for any suction noises. Could be the MAF, give it a clean and check for fault codes on vagcom.

If you've go a blow in the downpipe before the lambda it will cause problems as it won't adjust the fuelling properly

Overkill much on the fuelling!

Overkill much on the fuelling!

nope done a 100 mile journey on £15 max the other day with a blowing exhaust pretty good compared to my track 106 lol

Replace the temp sensor first and see how it goes
