Mpi Engine - Won't Acelerate More Than 2000Rpm (Video)

[diogosctomaz]

Hello all,

I have a Mini MPI from 1998 (Monza Edition) and since five month i facing what it seams electric problem. Full throttle won't reach more than 2.000 rpm as you can see on the video.

I already change:
- Ignition coil pack - MPI
- Spark plugs
- New plugs
- Relay
- ECU with FOB
- Crank sensor
- They verify the lambda sensor also
- They verify the injectors and they are good (went to a specialist)

The weirdest thing is... the car sometimes is working good, then after a while (after he gets warm and smells a lot of gasoline) the problem appears... Do you think that is anything mechanic? What more things that i can see?


They also check the cat, and also check the exhaust and they are functional. The code reader didn't detect anything...

About the throttle position sensor, if its with any error the code reader will detect that?

(I'm so tired of this problem... and the worst thing is.. im in Portugal and no one can really understands this MPI engine... imageimageimageimageimage )

Change the fuel filter first, also it may be worth taking the tank and fuel pump out, check the strainer at the base of the pump unit, and give it a really good clean, they block, and loads of washing up liquid massaged into them and rinsed out helps a lot. Trace the fuel smell, it can only be from something leaking can't it?

Anyway, it's worth a try
