VRTrickster 0 Posted January 22, 2007 Report Share Posted January 22, 2007 Right some of you will know that Ive had lumpy idle and cutting out problem for f-ing ages now, and it really puzzles me what the problem is! On the up side its booked into Stealth on Friday for a remap, that's if its possible to remap ! Just a question, why would taking the vac hose off the fpr stop it from stalling ! When it cuts out it does just dies, the revs drop quite fast then the ignition lights come on. This is happening regular, but taking the vac hose of the reg seems to stop it stalling, but you can see sometimes the revs dropping faster than it would normally, as though it would of stalled with the hose on ? The fella that done my head work did say that it would need remapping straight away and that it would be running rich, as old ECUs would chuck it so much percentage of fuelling. Others have told me that it should run fine as its all governed by the MAF, Lambda probe and sensors etc ? Any advice would be great, I think I may have to leave it to Vince to diagnose, or maybe it does just need remapping ! My worst fear is to drive all that way and for him to say that the cam timing is definitely out, as I'm certain its correct ! Link to post Share on other sites
jaysVR6 2 Posted January 23, 2007 Report Share Posted January 23, 2007 If you warn Vince that you suspect the cam timing is out then its not a difficult job for him to rectify. Quite how your mechanic would manage to get that wrong is beyond me as he should have used a key to lock them in place.There is also no way the car will just cut out and not run correctly after having the head rebuilt, even if you've had the s**t flowed out of it. I would suggest you have a blockage somewhere.Be prepaired for Vince to want to keep the car for a day or so if you haven't prepaired him.One tip may be that if your planning on any further mods, i.e exhaust or filter or any other significant parts like exhaust manifold, don't have it mapped yet because to be honest, if the head is all your getting it mapped for you're spending alot of money for not much gain. (unless it's got different cams of course).He may find your stalling problem for you though. I would ask him to find the fault with it first, as if you just chuck money at it and ask him to remap it, he'll just go and do it at the cost to you and you'll still probably find it stalls.Hope this helps a bit Link to post Share on other sites
VRTrickster 0 Posted January 23, 2007 Author Report Share Posted January 23, 2007 I actually carried out all the engine work myself as it goes, so Im sure the timing is correct !I have carried out quite a few mods :264 cams, re pro TB, port matched and flowed inlet mani, gasket matched exhaust manis, gas flowed head ,mk4 head gasket, BMC CDA, alloy flywheel, sytec fuel pump and low temp stat and switch. This is why I feel its ready for a remap!I am probably going to fit a s/s exhaust and high flow cat at some stage and vince said it would be fine as he gives the map extra percentage of fuelling for say further mods.Im thinking the problem could be down to the FPR, which I have now ordered and should be with me before Friday, so I can only keep my fingers crossed !
