Popped down to Regal for a remap on Saturday and all seemed fine until the Sunday night when I had to go to work!
Started the car and the revs started surging upto 1500 and down to 500 RPM realy fast- fast being up and down within a second! It wont drive like this and if you try it'll stall! This lasts for approx 2mins then the car drives of singing and dancing as though it's done nothing wrong!!
I have rang Regal and he's adamant the software is 100% ok and it must be the hardware ie a sensor or something like that at fault!
It's booked in at Vx on Monday so they can have a cold start on Tuesday but has anyone any ideas please??????????
