I have an RXDI 2002 that idles good on land. The second I give it gas, it dies out. If you puch the throttle very very sensitive you can get it to run up to over 6000 rpm on land. In water it´s very hard to get started at all. This fault is coursed by a flipp a year ago. When they flipped with it they removed the spark plugs and ran it dry. Then they took it to a dealer that took care of the rest. The dealers BUDS don´t show any fault codes. The machine it selves don´t throw any code. The dealer has no more thoughts of what could be wrong.
I´ve checked the comp. and it´s good on booth cyl.
I´ve checked the fuel pressure to the air/fuel rail and it was 107 psi as it should be and it´s constant even when you throttle
I´ve also checked the air compressor and cleand the air intake to it, it works as it should.
I´ve checked the RAVE system and haven´t found any faults.
When you remove the spark plugs they are very sooty on both of the cylinders. I get the feeling that it gets to mutch fuel, if you compere to the amount of air it should have.
If it don´t gets the amount of air it should, it could be sevral things:
Has anyone had problems with their reed valves? One theory I have at the moment is that the reed valves is open on both cyl. so that the internal pressure in engine isen´t enough to keep the air flow up when you start to throttle...
If there is something wrong with the TPS shouldn't´t you get an indication from the meps then?
Isen´t very odd if both TPS sensors fails at the same time? Or even if something is wrong with the air sensors shouldn´t you get an alarm?
I don´t get the feeling that this is an wirering problem on my machine. When you throttle the machine it feels like the choke is on. The only problem is that the DI machine dosen´t work like that.
