    Throttle body balancing screw - QP 3.2 Evo

    Hi all, Is there any logical way to adjust the balancing of the two throttle plates on the 3.2 throttle body ? These are calibrated at the factory and then the screw is sealed with a plastic plug. Not to be touched. Last mechanical problem I had with the car was when I had a high rpm/uneven...

    Climate control not working

    Starting the QP Evo for this season revealed an annoying problem. There is no life in the climate system. Panel is dead and fan not blowing. The usual loud "click" from AC compressor is also not present. Fuses are checked and OK. There might be some relays involved but the only ones I find are...

    Engine in limp mode when warm

    Hi all, My QP Evo 3.2 has started to act up recently. It will go into a kind of limp mode when engine is all warmed up. Not sure if it's limp mode but it will suddenly start to run very uneven and not on all cylinders. There is also a strong smell of fuel and engine is very down on power. This...

    Workshop manual Quattroporte 3.2/Ottocilindri

    Hi, I have this manual in german but would really like an example in english. Anyone have an idea where to download safely ? It would help just to have torque settings for gearbox and clutch to start with. It's on page 7 of "Technical Data" chapter. I'm replacing the clutch soon so correct...

    Clutch pressure plate 3200GT

    Hi all, Where can one get a pressure plate for the 3200GT or a QP 3.2 for that matter ? Both Eurospares and Superformance have no available parts and I can't seem to find any on ebay etc. I have sourced the clutch disc and the release bearing but not the pressure plate. It's rather...

    Differential QP 3.2 Evo

    Hi all, Are these differentials ZF or Maserati/Ferrari derived ? I think I need to rebuild mine as it has started to clunk heavily whit on/off acceleration. Might be easier and cheaper if it was German derived. A

    Timing belt tensioners

    Hi, Just found out that the very expensive timing belt tensioners for some of ours Biturbo's are really not that expensive after all. I'm not sure if this has been mentioned before but thought I'd mention it anyway. Tensioner for QP V8 Evo and Shamal is also used on Mitsubishi and Hyundai -...

    Idle speed cold engine - QP4 3.2 Evo

    Hi all, I've got an irritating problem on my engine. When cold it idles too hight,aprox. 1600-1700 rpm. After a few minutes it starts to settle down but will then fluctuate between 1000 and 1400. When warm it settles on 1000 rpm. I've tried to adjust the air flow potmeter on plenum but can't...

    Diagnostic contacts - QP Evoluzione

    Hi all, I've been searching for the diagnostic contacts on my -98 QP 3.2 Evo. I thought they where on the same place,right side footwell under glovebox near center console,as the pre-Evo cars - but clearly not. The only two spare contacts I have found are in the right side footwell against...

    Steering lever and bushing - Quattroporte Evo

    Can anyone tell if there is a difference between the older bushing - 326656348 - and the new - 376690348 for the steering lever 376690147 ?? My dealer say they are the same and can be used either way but I thought there might be a reason for the newer part and the double price.... I think I...

    Low oil pressure warning light - 3200GT

    This may have been discussed before but I can't find any answers. Why do these cars,along with my QP Evo 3.2,have a low oil pressure warning beginning at 2,5 bar ? I've seen it on other cars and along with mine it warns of low pressure as soon as the needle is near 2,5 bar. It's really...

    Intake cams - 3.2 V8

    I've always wondered about the tuning performed on these cars by Modena in Germany. They alter the timing of the intake cams to get more HP - but when asked they will not disclose details. Understandably. Does any of you know more details ? How many degrees have the cam setting been altered ...

    CEL - Check Engine 2.8 V6

    Hi all, Trying to sort out some problems on a 1996 QP 2.8. We get "Air/Fuel Ratio" code - flashes 1-4. Initially we found that both water temp sensors where far out of spec (6K and 15K) and changed those. That didn't cure anything other than better exhaust gasses... Then we found that the...

    Airbag light - QP 3.2 EVO

    I've had this light for a while but do not know where to begin searching for faults. It's an old system on these cars so I was hoping it wouldn't be that much to check :-) I've looked at the connectors for main airbag and also the passanger - looks ok. Today I checked the airbag central unit...

    Galloping idle when cold - QP4 Evo 3.2

    Hi all. I have an annoying problem with the QP. In cold weather,below 0 Celsius,the engine starts with a very high idle. Usually about 1800-1900 rpm. This is of course wrong and very annoying. It will keep this idle for a minute or two while the engine warms up,then it will start to rapidly...
