Hoping someone can help. Still the ongoing saga with the car that cuts out at ignition. Changed EGR and checked intake manifold (no crud) over the weekend. Car ran fine since then, this afternoonI started it after driving a while and it went lumpy at idle kinda like fuel starvation which it was doing before, I did what I did last time and unplugged the MAP sensor, started again and all was fine.
Plugged MAP in again, same thing, idles then dies. I noticed when the car died and I stuck my ear to the drivers side headlight a hissing, took off the air intake nozzle and it was definitely coming from infront of the airbox and behind the headlight. Looked like a few pipes go into some thingies, are these the N75 or ? As I think they may be the problem.
Drove car home without MAP sensor plugged in, obviously no power but it never died once in 20 odd miles. Strange thing is I plugged the MAP sensor back in after the run and all seemed fine again, put ear against airbox area and hiss was gone! Gotta be intermittent, so thinking a valve of some sort?
Thanks in advance guys for all the help with this PITA problem.
