Am still suffering fuel starvation problem when exiting sharp corners, particularly rounabouts. Can anyone help with the following questions ?
1). What are the fuel line pressures for an STi 4 ? Same as UK ? 2). Is the height of the fuel intake in the tank adjustable ? 3). What is the purpose of what appears to be a breather valve on the tank ? This is not present on UK spec. cars. |

the fuel pressure should be 41-46 psi at idle. height of fuel intake do you me where the engine gets its fuel from,if so the tank unit under the rear seat has a filter at the bottom and the height is not adjustable. i suspect | || || || || || || || || || || ? the fuel tank has two chambers and is provided with a suction pump which transfers fuel from one chamber to another,if this is faulty it would cause the problem. let me know how you get on peter 0161 224 1431. |
Yesterday I turned right on a roundabout in a 4-dr STi V5 and went to overtake a slow moving vehicle 5 or 10 seconds after exiting the roundabout. At approx 3000 rpm in 3rd gear I depressed the accelerator expecting to get good boost and the engine more or less died on me, though it had been ok since the slow exit from the roundabout.
I changed down and everything seemed to sort itself out. I'd just filled up with Tesco premium unleaded incidentally. Does this compare with what you're experiencing at all? Brendan. |
Problem occurs after passing apex of turn, a second or so after the throttle is depressed. Problem starts at about 1/2 tank of fuel and gets progressively worse as level decreases. The effect can be generated at will.

I too have had similar problems with my 4-door STi V.
This has been on right-hand bends, esp. roundabouts, however I only seem to get the problem when the tank is registering 1/4 full, or lower. Maybe I'm not driving fast enough to get a problem with more fuel in the tank?!! - But I doubt it!! |
