Just been out in my lex and it died, lost power in 1st 2nd and 3rd, pulled over for a few mins to let it warm up a bit, and it then drove like a rocket, hit 0.4bar on the gauge a few times and the SSQV went very loud? feels like fuel starvation at first when cold? but drives fine when warm? any ideas?? :confused:

I know Edeath said he had the same problem with his but a new fuel pump sorted it out? i do have a spare standard pump in the shed so might swap it over to see if it does anything? :confused: plus i'm going to order a new walbro 255lph pump in the next few days/weeks?

No mate, sure its something to do with the fuelling as it stutters/miss fires when cold?

Isn't there a fuelling problem fault code though? And a misfire code, depending on which cyl.?

Would bigger injectors make a difference?

Mate sounds like a fueling issue when cold but it sounds like it could also be a coil pack?

The problem I had with my charger was between 2500-3000rpm it would lose power slightly and then kick back in again. It was worst when cold and almost went away when warm but I could catch it out on purpose if I want to by flooring it at 2600rpm. I problem felt exactly like the traction control was kicking in so had to be injector/fuel related.

It was diagnosed as a fuelling problem by SPC and they installed a 225 pump in the car (I wish I knew the brand as it only cost £100) and this sorted the problem out. However the problem came back as soon as I installed the exhuast manifold so I'm not sure a new pump is the definitive answer. Also the current owner of my SC kit had the same problem when he fitted it to his car.

Walbro, surely. Mine was £70 (and it's definitely genuine) and the only difference will have been the fitting kit.

That would make sense as a Walbro Supra pump is about £100.
