umonkeyz 0 Posted May 12, 2010 hi, i wonder if anyone can help me out. my 1995 vr6 has started to have serious starting problems. ive tried the search function but cant find the exact symptoms. the engine turns over, but then the revs drop straight back down and it dies. if i give it some gas the revs pick up to 3-4000 then dies again. it starts eventually after about 15 attempts (embarasing in a busy petrol station!) it runs mostly fine once its going, maybe very slightly lumpy at low revs. it did have a minor starting problem and slight lumpness at junctions when i bought it a couple of months ago, so i fitted a new ISV myself and it seemed to fix it for about a week. however now the start up problem is much worse. from what ive read i think it may be the MAF sensor. ive also read to check the fuel pump relay, i dont know much about either of these parts so ill have to read up on them and check them out at the weekend before i give up and take it to my local indiependent. is there anything else it could be? thanks. sam.

Reggit 0 Posted May 13, 2010 If it was me I'd change the usual 3 suspects first if you don't know their history: ECU Relay Fuel Pump Relay Ignition Switch It'll be also worth scanning with VCDS to see if any odd codes are stored which could account for the problem.

V33DUB 0 Posted June 19, 2010 Did you find the source of this problem as my 8v has started to do the same intermittently. :( Quote Share this post Link to post Share on other sites
umonkeyz 0 Posted October 6, 2010 For info i finally solved this! It was the flaming immobiliser! Hopefully sorted by wd40 on the immobiliser contacts. Quote Share this post Link to post Share on other sites
