So..When I rev it up..it stops at 4 grand and somewhat bounces. I have an AEM wideband with the gauge and my readings are this. At idle, its higher than 17.0 A/r..the guage flashes then reads nothing cuz it leans out so bad..So my idle is very poor, and around 600 rpm. When i rev it up..the A/F completely swithes around and i hit lower than 11.0 A/F at around 4grand..which makes it bounce and not rev any farther cuz its getting way too much gas. My question is this. What could it be? I was thinking it might be the Fuel pressure regulator, but I'm not sure. Please give some input. Car is an 86.5 7mge-T with 440s, walbro 255, and stock turbo FPR.

what kind of AFM do you have..and yes it could be a boost leak..check all the hoses..especially the big hose on the turbo..they tend to get loose

If you have a turbo AFM Id bet on a boost leak. Check your fuel pressure and we can help you out more.
