My 3.2V6 is suffering a power loss problem.
Regardless of whether the engine is hot or cold, it's absolutely rubbish off the mark. It feels more like an asthmatic 2.5.
When you hit around the 4,000 rpm mark, there is a sudden, very noticeable, increase in power, the engine will then pull like a rocket up to the redline.
The first thing that went through my head was a multiram problem.
Both multirams are plugged in, and the vacuum pipes are routed correctly. If you pull the vac pipe off the rear multiram, after having the engine running, there is a good hiss, which indicates the vacuum tank is working?
Unfortunately I can't do actuator tests, because I don't have any equipment at the mo to do them.
The only things I can think MIGHT be making a difference (advice on this please) -
1) The servo to plenum main vacuum pipe is from a 3.0, not a 3.2. Therefore it has two vacuum outlets. One vac pipe is going to the vac tank, and the other to the heater system. The correct configuration on a 3.2 should really only be one outlet on the servo pipe, and both the vac tank feed and heater system connected via a t-piece. But essentially the same is achieved?
2) The fuel tank purge valve is electronically connected, but at present, due to the connection on the purge valve being broken, the pipe from the tank is going straight into the plenum, so essentially it's behaving like it's always open. I'm not sure what difference this would make, but I'd like advice please.
I do intent to rectify both of the above ASAP - they were just niggles during the rebuild.
Otherwise -
- Compression fine
- Timing spot on
- Plugs etc new
- No fault codes, other than for the secondary lambdas..
Advice welcome please
