AndyMac 0 Posted August 9, 2005 Report Share Posted August 9, 2005 I have an early 4motion, which seems to have a helluva alot in common with obd2 Vr's (the ignition is identical from what I can gather) basically my cars performance, so bad I knick named it slowmotSeriously I have sacanned it fro faults, nothing my maf was reading persistently low so I replaced it, i replaced all the plugs and tested all the ht leads, i also found a small crack on the coilp pack which i checked for leakage and then did the araldite fix, I also did some checks with vag com and misfire counters and they are all OK, so seen as you guys are alot more technical than my usual hangout, (www.uk-mkivs.net) could you give me some nice hints and tips.

vr6turbo 27 Posted August 9, 2005 Report Share Posted August 9, 2005 put it on a rolling road and check out how the a/f is being managedthen if the a/f is correct and the engine is not throwing any codes i would look at restriction in the exhaust system ie cat has disloged its core and is retricting the exhaust flow long shot but worth checking its all i can think of not having any experinece with mk iV'sif the engine is running at the right air fuel ratio and the vagcom is showing clean there are not alot of options leftgood luck keep us posted Link to post Share on other sites
