I have been having some recent problems with my rb25. It seems to be popping and back firing when acceleration between 4 and 7 rpm. I have changed coil packs, spark plugs, igniter box even the coil pack loom and still no luck.
I thought it could possibly be something to do with my fuelk system as it seem sto feel like fuel cut when it happens. If anyone has come across the same problem could they please e-mail me on,
[email protected] as i have done nearly everything and ready to give up.
Thanks, James
