andy 0 Posted May 26, 2004 Report Share Posted May 26, 2004 The VR is doing something strange, any experience / suggestions appreciated. Its like it doesn't know whether to pull or not. When I'm doing 2 to 3k revs, if i try to accelerate the car bogs down and feels like I have put the brakes on lightly. If I then ease off the loud pedal it seems to feel happier. If I push it hard its fine. Also noticed its reluctant to start cos it wants to idle too slowly. I'm sure the plugs and leads are ok and have checked the whole idle valve thing.

Mangold 0 Posted May 26, 2004 Report Share Posted May 26, 2004 MAF sensor maybe? Link to post Share on other sites
andy 0 Posted May 26, 2004 Author Report Share Posted May 26, 2004 i was wondering about the cam position sensor, unsure what symptoms this would cause though Link to post Share on other sites
acf8181 0 Posted May 26, 2004 Report Share Posted May 26, 2004 could be any of the above, or old fuel filter, leads, plugs...best thing to do is get the diagnostics checked for fault codes. this will hopefully point out which it is. Link to post Share on other sites
apd 0 Posted May 27, 2004 Report Share Posted May 27, 2004 maybe hall sensor?this is in the coilpack that sends the signal to spark.worth checking the wiring and earth connections. Link to post Share on other sites
Macca 1 Posted May 27, 2004 Report Share Posted May 27, 2004 Im just experiencing exactly the same thing!Sometimes car is fine but sometimes under load the acceleration cuts completely and car 'bucks' badly, press the accelerator and nowt happens, engine keeps running tho. Wait a few seconds and its fine again.I changed the fuel filter yesterday but car is still the same. Got it booked in next week. Let me know how you get on Andy! Link to post Share on other sites

andy 0 Posted May 28, 2004 Author Report Share Posted May 28, 2004 right chaps, mines sorted! should have known it, was further problems with the idle stabilisation valve pipework. Have been having problems with this for about a month now, found the contents of my NEW! sound deadner wedged firmly in the pipe leading to the valve. Only replaced the old one about 2 weeks ago for the same reason, looked closer and found the spongey stuff was melted and have realised that I have had problems in this area since I changed to a RamAir filter, basically the air I am now sucking in is so much hotter than with the proper airbox that it has fried the contents of two sound deadners in two weeks. The new deadner came with a heatshield facing the exhaust so they're obviously prone to heat damage. Hope this helps... Link to post Share on other sites
FishWick 21 Posted May 28, 2004 Report Share Posted May 28, 2004 Take the noise damper off, they're more trouble than they are worth. I dumped mine yonks ago with zero adverse effects. Link to post Share on other sites
Macca 1 Posted May 28, 2004 Report Share Posted May 28, 2004 Very interesting, i installed a ram-air a few months ago.any chance of some pics so i can check if my problems are being caused by the same thing?Or could you describe exactly where the idle stabilisation valve/ noise damper/ pipes are?
