Ok, I need some help from the Volvo Gurus here. b230f with Bosch FI. Has lean condition and stumbles badly off idle. New main pump and in tank, fuel filter and tried two different regulators. One new and one know good one but problem persists.
Pinch off the return line and it runs perfect, shows no codes. New cat, AAF, TPS , knock sensor and temp sensor. Changed the blck control box and fuel pump relay as a last ditch effort, no change.
Don't have a fuel pressure gauge to check pressure at the rail.
Any ideas?
Thanks!
