Hi folks ..me again .
Basically had this problem before ...spoke to markey mark and thought the best option was to get a carb that worked overhauled and sent up to me .. so fitted that carb ..took it small runs ..like round small roads etc and it seemed fine.
So i thought ..everything was all well ..took it to Millers to get the carb jetted for 1bar boost. ..before we did that we took it on a run with the wideband ..all was fine till i let t he car settle ..put it into 5th gear and tried to use a wee bit of throttle ..it kept juddering(making the car shake like hell). So we got it back to chris's ..he checked it all ..noticed i hadnt had my throttle cable on properly so was only achieving half throttle. Sorted that ..he sorted some bits and pieces ..cleaned it up a bit ..we took it a run again ..checked the AFR's on boost ..he said it all was fine. It did however pop and bang on overun. Chris then said he aint touching any jets untill it can drive off boost first ..which is what i want first lol.
So we left chris's and he told my mate reco to check and clean a jet on the carb. Then on the way home ..it got worse ..got the point it would only drive on boost .
So my mate reco took the carb down and cleaned all the jets out and the tube bit that lifts out(i dunno what thats called ). Put it back on the car ...it revs up ..but if we keep it at a constant 2-3k (unsure what rev range as we were at the engine bay) it would hessitate/judder ..almost act as if it had a missfire.
What could it be? ... since being at millers house we have changed the fuel filter and changed the fuel pump from a clio 1.2 one to a clio williams pump. and weve cleaned the jets.
I took it a drive the other day and it would cut out at junctions ...but it was fine when it was properly warmed up...but it still hessitated. Its stumped me if im honest ..its a hard one to describe over text .
Cheers
