    the only sedona @ that year 05 has a kv6 petrol engine in the uk market but may be differant elsware

    another answer is the cam sensors plus the crank sensor recieved by the engine control module might be running the engine wrong because the valve timing is incorrect and over advancing the ignition because the engine has warmed up i still think the valve timing is the prob the inlet cams

I think your car has got the rover kv6 engine and am sure the camshaft timing is incorrect. i worked on these engines and they are 2 different timing tools for the cams depending on the engine. sounds like they have used the incorrect tools on the rear cam belts there is 3 belts on that engine. the 2 at the back have timing positions 1 for 2ltr the other for 2.5ltr the engine control module gets confusing signals from the camshaft position sensors and will cause that problem. take it back to them and check.

    05 Kia Sedona only has 3.5 L engine. You might be thinking of different model? I agree camshaft timing could be problem. But why does it run great cold and ping and lose power when warmed up?

SOURCE: Have a 1997 Dodge Neon

Let me start by saying that my profile says computers, however, I was a mechanic for years. Developed arthritis, and had to find a different career that wasn't so ******* my hands.

The way the timing belt system is designed on these, when the belt breaks or jumps time, it generally causes damage to the valves. I'm also going to recommend a compression check to see if one or more valves were damaged. If you have damaged valves, then this could be the cause for the rough running and the timing code. Start with a compression check and let me know. We'll go from there.

1993 jeep grand cherokee loses power at operating temp.

ever do a real tuneup this decade
spark parts, and filters. that be first
and make sure the hot engine (sized not stated) is really hot.
180F or more, and holds, it must reach normal spec, temp.
or the ECU brain will not do its job right.
the only clue I have here is skips
skips must mean misfire.
there are over 50 causes of misfire.
bad spark plugs tops the list.
and all spark parts there, cap/rotor,wires set this OLD.
car is old , needs a major tuneup

they to forget all that other stuff, and elaborage
what skips means.
i guess never cold does it skip.

taCH DROPS TO ZERO BUT engine not heard to stall?
if yes, electrical problems or CKP failing?
what does engine do when TACH does that, matters big time.

I keep getting a pinging noise like i have bad gas i have run premium fuel i used lucas fuel treatment and seafoam no change

You could have an engine that is running hot or your timing is out of adjustment. If the temp guage is still showing normal you could still have a hot cylinder usually caused by the computor leaning out the gas mixture in response to a too rich gas situation it perceives to occur. If the timimng is out of adjustment it needs to be tracked down, a worn timing belt or perhaps a loose sensor.

You definately should have the truck looked at by a professional soon. If not then you could be faced with large repair bills when the engine lets go. Hope this helps.

2003 Kia Sedona charging system

This is typical. When cold starting/running, it takes more amps to run. It is using amps for higher idle to warm up engine, Altenator is spinning faster, and all sensors are being used at same time.
This is why mechanics say wait til normal operating temperature before any testing is done.
Once the engine hits normal temp, the computer readjust voltage amps, fuel pressure, air intake, timing and more.
