vtr/s conversion engine trying to cut out
 

hi all just had my vts engine changed as it was dead, put a vts in there and it has been fine for about 100/200 miles then the temperature gauge went funny it just goes up and down ?

so i was driving today and the revs started to go down so i just left it and the engine cut out then, so i turned it over and it fired back up straight away but now it keeps trying to stall but not all the time any clues ?

my engine loom was crossed over from mk 2 vtr to a mk1 vts could it be the looms are or is it to do with maybe the sensors or coil pack, i have cleaned all the sensors on the throttle

Any help pleas would be great as this is my drive to work !

it sounds like it could be the loom mate but first i would check coil pack m8

another thing to check would be your ht leads

okay thats basically means just buying another coil pack right and taking the chance and see if it fits or not ? as i cant get hold of another coil pack but i just started it and it seems fine i will give it a run when i get time thanks mate

I did read something about there was a loom that wasn't quite right for the fuel pump? Your problem sounds like when my fuel pump broke on my vtr too:y:

Wow this is my exact same problem.

any help with this?

if its stalling i would have thought eather fueling froblems or ideling problems

I have had the vts fuel lines plumbed in though the return line, i will take it to the garage and see what they say and what ever the problem i will post with a reply thanks for all the suggestions

just to say i did unplug the idle control vavle conection a few times and drove 20 miles and it has not happend since ? maybe its okay now

Could be the idle control valve causing the bouncing revs, the temp gauge problem could be a faulty connection somewhere or you may have an air lock in the coolant system.
