It might conceivably be worth checking the engine oil level. If you ignore the handbook like I did, and check the level when it's cold, you'll have too much oil. This tends to come out as smoke from the left side (when behind the car) exhaust. Just a thought; I'm afraid I can't begin to help with the rest of your queries. | ||

Frank, do you have that manual...if it possible to get a copy of the procedure...James and I will try to test fuel pressure tonight. Any help would be greatly appreciated. | ||

Hi.......... According to the Ferrari workshop/repair manual for the Boxer, the fuel injection system is comprised of two Bosch K-Jetronic units. The Ferrari manual called "400i Injection - Principles of Operation, Checking and Diagnosis Procedures" should be employed to address problems with the system. Good luck !!

well, I found a friend who used to be a MB mechanic...he is going to bring me his pressure testing kit in a few days. When he does, I will give you a call, and maybe we can get together and solve this problem | ||

well, I am advised to plug in a fuel pressure tester (where do you get one of those?) between the WUR (warmup regulator) and the FD (fuel distributor) and measure the fuel pressure. James, you have any idea where to get one? | ||

Thanks for the info rich. I'm going to dig out my old portable 02 reader. Worked very well when trying to tune a 540" beast of a motor  He did have the FD rebuilt, but I feel that it is possible it was not done to spec. I'll dig out all my bosch books tonight, this problem will anoy me until I can figure it out hehe.. Thanks James | ||

Sounds like you need to have the pressures checked in the system. This would help isolate what the culprit/s are. A CO machine would be the best way to adjust the Bosch CIS system. If the WUR is "stuck open" then it would be extremely rich on that side plus the WUR would have lessened the pressure by being stuck in the open position. Did he have this fuel distributor rebuilt? If so has it run right since then. Many have told me that there cars never ran the same after they had the FDs rebuilt. On the WUR you can knock the pin up/down to see if this helps. This would change the richness and operating pressure. | ||

Hello, I do not own a Ferrari(yet), but I did get to mess around with a few today. I'd like to thank Coach for letting me come play with his toys Anyway, after looking at his Boxer with him, I thought I might ask here again to see if anyone has any ideas. From what it looks like, the right bank (passenger side) is running on the rich side. You can hear the "poping" of unburnt fuel in the exhaust, loud at times. The car also will shut itself off after a rev session when trying to re-gain it's idle. He has had the fuel distributor rebuilt, and I thought this is where the problem lies. After backing off the brass adjustment screw a quarter of a turn (located to the right of the airbox between air meter and fuel dist), the poping was reduced and the overall idle improved. However, it was still running on the rich side under load. Now, I wanted to make sure that this adjustment screw was the correct one on an f-car to fine-tuneing the mix. If not, where is it located? Also, is there a port on the exhaust somewhere to hook up an 02 sensor? Does anyone have the OEM range for the correct mixture? Also, what is the proceedure to correctly set the idle sync for both banks? He had said others have suggested it was his "dinoflex" which as I understand it, is the ingnition system correct? The car does crank, it idles somewhat well, and does rev through the range without falling dead on it's face or cutting out completely. Does this still sound like a possible ignition issue? I know nothing about this system, other than it is expensive :lol: Oh, and does the exhaust cross over in the rear? IE: Drivers bank exit on the passenger side? The reason I ask is that the drivers side exhaust had some whiteish smoke comming from it under load. Couldn't really tell if it was blue, but it was not "heavy" blue that is for sure. But the other side did not have any smoke of any kind, but the exhaust speed/strength was much lower than the drivers side. His plugs looked good on the drivers side bank, but they were fouled pretty nasty on the passenger side, which is why I was thinking fuel. Is it possible the warm up valve is stuck open? I was going to recomend to him that he change the plugs and start fresh, coudn't hurt. Anyway, thanks for any info! James |
