i have a 2000 sedona sx petrol 2.5, which i must admit to seriously being in love with!!! until this, had serious poping from the engine and not reving beyond just over 3,000, also the management light came on. hooked up to a rather impressive machine and told the lambea sensor serving 1,3, and 5 was faulty, had it replaced. Shrek (the kids named it) was still no better so alll sparks-even the back ones!- were replaced along with the leads and filters, slightly better will actualy go over 50mph now but still rubbish. So here are the symptons!!! When first fired up it will run perfectly for about 2-3 minutes and then suddenly goes into limp mode again.
All the air way pipes have been checked, so has the fuel pump and the air mass meter has been replaced too.
So if any of you experts would help a damsel in distress i would much appreciate it- i am now at the point were i no longer want the kids in it incase something drastic happens.......please, please help me!!!

Shrek.....it must be green.
Now apart from a rather obtuse bit of advise I received some time back when we had our own 2.5l v6 Kia Carnival that all green cars go pop and are lemons I think there may be another type of mystery operating in your car.
I am not 100% familiar with the carnival setup but I would say the reason that the vehicle is running fine when it is idling is because the air/fuel/spark side of the vehicle is controlled via the idle air valve. So at least this part is working. Onto the next part when the vehicle is warmed up the load of the engine and the air flowing through the vehicle are used to calculate the amount of fuel that is needed and it is here that the problem is hapening. At seven years of age the vehicle could have any one of a number of sensors that are getting to the end of their life. But I must say that a lot of money has been wasted as randomly changing out parts when they are still functioning fine is not the answer and It concerns me that the mechanic looking after the vehicle is taking this route. All the sensors can be checked for their output and put simply they can do something called datalogging which tells them exactly what is happening in the engine as it is running poorly. Something as simple as a vacuum leak or fuel filter clogging or fuel regulator failing may have been causing the vehicle to lean out and cause a misfire and put the vehicle into its limp home mode. Also it could be as simple as the throttle position sensor failing in some manner leading to incorrect amounts of fuel being put into the cylinders. Again it is a matter of methodically going through these areas with a bit of detective work and not just randomly changing out plugs and wires/mafs etc.
My strong suggestion is take it to another mechanic (recommended by someone you trust) and get a sensible diagnosis of which aspect of the engines operation is failing Air/Fuel/Spark.
Hi, thanks everso much for your reply, its really helpful and yeah it is green!! The mechanic working on my car is a friend and is doing all the work free, well for a bottle of wine, I'm not in the position financially to put it in a garage......especially a kia one.
The parts he changed had all been faulty and the rear plugs looked as if they had never been changed which really P'd me off because up until this year i had always paid a fortune for services which obviously weren't being done!!
The chap has checked the cylinders that he can reach and the front ones are working ok, but the rear ones dont seem to be, also there is no management light on anymore since the repairs but shrek is still not working properly although it is far better since the repairs. One big problem is he knows it has a rover engine but not sure which one and where the hell do you get a manual???? Any ideas??? I really appreciate your help to date

Yes sometimes the stealerships can really do the wrong thing by customers. Glad to hear you have a trusted friend who is willing to help out. Does surprise me that so much has gone wrong with the car. But of course the big downside of the 2.5l kv6 based kia engine is the failure of the cylinder liners. This affected a lot of vehicles down here in Australia, some 40% (possibly more). For us when our cylinder liners managed to destroy the engine for a second time and KIA would not pay up it meant selling the car at a huge loss and remortgaging the house to get another car.
So I guess the vehicle has been checked for any problems with the head gasket being compromised due to the cylinder liner fault?? Easiest way to check that one is compression test/ensuring there is no oil in the coolant.
As far as a workshop manual, well I guess it is a secret?? because I had similar problems finding one at a reasonable cost back a year ago. I did find this on a web site

Kobus Says: August 26th, 2006 at 6:02 pm Im looking for a workshop manual for a golf 2 gti can any one help me?
I have tryed google and have had no luck. I have the workshop manuals for most of the late model kia’s my e mail is kobusvantonder@yahoo.com
Apart from that there seems to be nothing available. Certainly the similarity between the early rover kv6 engine and this one in the KIA is very similar so I would think it would be easy to get the information. I know that KIA have a world wide diagnostic site but from memory that only included the american engine.
There is a company called autodata, but again as I have found with finding information for our current vehicle mazda MPV they may well not have the carnival. Best to give them a phone call and find out exactly what information they have on the carnival.
Hi again,
Thanks for all that. The head gasket was replaced last year when the car blew up!!!!! what a surprise, i must say i would never buy another Kia again and i'm starting to feel quite venemous to the whole kia company!!! You are so right-Stealership is a very accurate term-£135 per hour to tell you nothing, and they can really drag those jobs out.
If anyone has any other ideas please let me know.......OR does anyone have a large can of fuel and a match???????

Neely, that is the same thought a friend in West Australia had for his Carnival, He thought maybe on the steps of Parliment it may get some attention to this dreadful act of Customer abondonment by KIA.
But just another thought, the fact it seems to be in like a limp home mode (only able to drive at a low speed) it would be worthwhile checking the crankshaft/camshaft position sensor and the output from these to see if it is within specification. Maybe something happened in the rebuild that has caused these to not provide the information the ecu (onboard computer) needs which will cause the car to go into a limp mode. Just a thought anyway.
Hopefully someone will chime in with some sort of knowledge, or is it like I suspect and all of the 2.5l kv6 engines are dying or dead.....
Replace the ignition leads they do go bad on the early carnival engines. When you bench test the originals they appear all right but they are not.
I have had a similar fault on my 2001 model and it was fixed by ignition lead replacement.

I thought neely said she had replaced those already.
