Hi I'm new on here and I'm having an issue with my evo viii gsr.
I've recently fitted a set of 274 cams but since fitment and map its taken longer to start so i though I'd change cam sensor to see if made a difference. I've now tried 2 different sensors both brand new and the problem I have is it'll either not fire or it'll backfire and cut out straight away. If I put my old sensor back in it Will start and idle/run fine with the exception of being lumpy due to cams. Anyone came across this problem before?
