Hi All, I'm new here, Look foward to chatting Mods and other things in the future, but for now I was hoping someone here would be able to help me with some problems my KR verada has been having.
A little background on the car, auto 3l v6, 92 model sedan, 130000ks, has dealer services in the book untill 80,000ks, dunno what's been done to it between then and 120,000ks when I bought it. It's had services as per the manual since then, I don't think the timing belt has been done, I will get it done shortly. fuel injectors have been cleaned at some stage, as it's obvious they have beeen removed from the car due to the markings on them. Always run on premium.
The are a few problems, but imainly awful fuel consumption and awful responce from the motor.
Consumption is up to around 18L/100ks, Throttle responce is extremely poor,there is not much difference between 1/4 throttle and 3/4 throttle at low revs, then at about 2700rpm you can feel a sudden improvement in the power delivery, so if you hold the throttle half way down, it will be sluggish untill 27000rpm where it will then accalarate at pace I presume it's meant to perform at all the time.
Up slight slopes under constant throttle, when under that magical 27000rpm mark, you can hear the engine note changing, like the fuelling is being changed, despite me not doing anything with the throttle and speed remaining the same.
I have taken it to mitsubishi, and asked them to check for fault codes, presuming that the o2 sensor, TPS or airflow meter might be playing up, but said it showed no fault codes at all, and suggested they remove the CPU and send it to melbourne for testing, $200 odd just to test it, with no guaranteed result, and me being without a car for about 2 weeks, and i'd hate to think what they would try to charge for a new CPU.
Has anyoe else had similar problems with sluggish v6's? what was done to fix it?
Other problems it has are:
if there is less than half a tank of fuel in it, It will stall around left hand corners if driven hard so it's producing high g forces, Is this a common problem, and I just need to keep the tank filled up, or do you think that the fuel pump/pickup in my car might be faulty?
And the last is with the auto, It changes gear on it's own accord, it will kick down gears by itself, sometimes even when just coasting down a hill with the foot completely off the accalerator, I took it to a shop to try and get it fixed, but when the guy drove it he said he wouldn't try to fix it untill the sluggish motor was fixed, as I would be flooring it so often to get past the sluggishness that it's probably confusing the auto.
Thanks for any help, Rick.
