Got an interesting 92-RX-7 in the yard this week.

Fixed many issues with it already such as fault codes, vacum leaks, air leaks, tank sludge etc & it was running fine but gradually over 10-miles has become a bucking pig. Even removed a dodgy boost bleed controller on the twin turbo's

No fault codes present. Almost every part swapped to be sure. Injectors removed & cleaned. 75psi compression on each rotor.

Feels like "limp mode" but its not possible this time

Question. Although fuel pressure gauge says there is 35 - 45 psi can there still be a fuel delivery issue such as "flow".....???

On the straight its fine. Boosts well etc. Come around a bend & try for any throttle & it bucks & carries on. Tank level = 70% full

Sure there could be a flow issue. You might have fuel pressure, but your injectors may not be delivering the fuel proper. Although, that doesn't sound like your problem.

Does it only happen on turns? If so, I would make sure things haven't broken off in the fuel tank and are getting in the way.
