z1000 Posted July 18, 2007 Posted July 18, 2007 Well had the chip and decat dp on a couple o weeks now but noticed when accelarating under full throttle it dies at 5 grand for a split second then pics up again and is fine, no probs in first and second and only doe it in 3rd or fifth when giving it everything but forth is the worst. If i give it 3/4 throttle its fine and boost gauge reads around the 1-1.1 but if i gun it and it misses it spikes to 1.3-1.4 Tried injector cleaner and cleaning the boost solenoid but no difference and the fuel pumps been changed to a 255 lph one so any ideas before i blow it up [:'(] Steve
gus the bus Posted July 18, 2007 Posted July 18, 2007 Steve, Have you checked the coil packs? sounds like the same problem as I had under load. I thought mine were OK but when I took them off all 4 had splits where the wires enter each housing. When these were changed that fixed the problem. Also, check for dirt condition of your MAF. Gus
z1000 Posted July 18, 2007 Author Posted July 18, 2007 Not looked at the coils yet but i'll have a go this wekend as i'll be in the garage fitting my ARB's and droplinks, maybe even struts if they get here in time [] What should i be looking for with the maf as i believe there quite delicate and don't want to go poking where i shouldn't [] (always gets me in trubble LOL) Cheers Gus and ur chariot looks great in the F&M pics btw []

ally-b Posted July 18, 2007 Posted July 18, 2007 Is it 'stutter'/'bogging' cutting-out ? or 'bang-your-face-off-the-windscreen' cutting-out ? Former suggests 'leccy problem (maybes fuel ,but I think you've checked that)- check coils ,plugs ,MAF. Latter , may be overboost - hitting max-boost cut-off momentarly - get map tweeked or fit boost-controller . Al.
johnnyr6 Posted July 18, 2007 Posted July 18, 2007 what chip are you using? as for some reason it's overboosting. Do you have an induction kit and what turbo are you running. It may be creep but i think it maybe down to the chip. Same as mine.
gus the bus Posted July 18, 2007 Posted July 18, 2007 Johnny, Steve is runnig the same Scoobyecu Chip as mine which is mapped for full decat and Apexi induction kit. I had the exact same problem until I did coil pack and MAF. Never missed a beat since[Y] Although it was suggested to me to fit an AVCR/boost controller just to keep an eye on things. Havent done it to date but may get round to it[:$]
wrxmania Posted July 18, 2007 Posted July 18, 2007 I'm sure you will Gus - can't be too much more you want to do to the beast now? When is it starting its' hillclimbs? Brian.
coulty Posted July 18, 2007 Posted July 18, 2007 Defo a coil pack. Been there done that. Not cheap for 4 but worth doing considering the age of these cars now. Budget £250 for all four. Shouldn't take more than 30 mins to change them all.
z1000 Posted July 19, 2007 Author Posted July 19, 2007 Its a proper smack ur head of the window job and the boost does jump so maybe a boost controller may be a good idea. Will check the coils at the weekend, where's the best place to get replacements ? take it second hand ones aint worth considering as they could easily be fecked too. Any recomendations on boost controllers as i know nothing about them. Steve
gus the bus Posted July 19, 2007 Posted July 19, 2007 Steve, Ebay is generally not bad for getting a set for £200 new. regarding the boost controller I was recommended an Apexi AVCR. Gus
z1000 Posted July 19, 2007 Author Posted July 19, 2007 I can get a set for £210 delivered through ebay, not what i really need after just buying new shocks but im sure the clutch can wait.
fai17 Posted July 19, 2007 Posted July 19, 2007 regarding the boost controller I was recommended an Apexi AVCR. Gus I ditto that[]
johnnyr6 Posted July 19, 2007 Posted July 19, 2007 Why would a faulty coil pack make the car hit 1.3 to 1.4 bar? If it is hitting 1.3 bar there would be fuel cut as the ecu cuts the fuel if bosst goes over 1.2bar (ish) This is exactly what my car did with a scooby ecu chip with full decat and apexi ind. kit. Funnily enough the same chip worked fine in coulty's car and the squirrels car with the same mods as mine but in my car it would hit 1.3 bar and cut, back off or use 3/4 throttle and it'd be fine. Was ok in 1st just happened when the car made full boost. Johnny
gus the bus Posted July 19, 2007 Posted July 19, 2007 Steve, Plenty of Apexi AVCR's in EBAY. I checked Indigo GT (where you got the induction kit from) and their price was a bit dearer. Gus
z1000 Posted July 29, 2007 Author Posted July 29, 2007 All sorted, new coil packs fitted and no more cutting out. Cheers for all the help [] Now a bacon roll to celebrate []
gus the bus Posted July 29, 2007 Posted July 29, 2007 Excellent! Thought it would do the trick[Y] Gus PS not heading to the borders today now (forgot about the footy!)think I'll be down next Saturday morning to the Lauder Common Riding as the Mrs is taking part (as always!)
z1000 Posted July 29, 2007 Author Posted July 29, 2007 Exactley what u said gus all 4 were split where the wires went in. A beautiful day like this and ur gonna watch footy instead of going 4 a drive, suppose it's better than being behind the lawnmower like i will be soon []
gus the bus Posted July 29, 2007 Posted July 29, 2007 didnae say a wouldnt be going for a drive mate[]! Just have to endure the footy first tho[] Just wont be as far as the borders unfortunately[]. Anyhoo, enjoy yer grass cutting[].......and glad the car is sorted[Y]
RA Dunk Posted July 29, 2007 Posted July 29, 2007 Now a bacon roll to celebrate [] throw an egg in it as well you know you want to []
coulty Posted July 29, 2007 Posted July 29, 2007 I just love being right lol [] Well done for just biting the bullet and hitting the problem straight on. Quite expensive but now you know it wont be the coil packs next time..... btw there WILL be something else that comes along next

Quite expensive but now you know it wont be the coil packs next time..... btw there WILL be something else that comes along next Cheers for reminding me [:S] My guess would be the clutch giving up the ghost. At the end of the day the whole lots gonna be replaced or upgraded sooner or later just part of modding cars i suppose.
