Ignition advance depends on several things happening. When in neutral there is high vacuum which sets the spark advance accordingly to be right for the mixture at the rpms
under load there is low or no vacuum so the mixture is different which requires a different timing setting
It was always known as timing advance on distributors but in many cases the ignition timing was actually retarded according to vacuum and rpms requirements.
If there are no codes being recorded then the electronics are doing their job.

I have a 2001 Mitsubishi Montero sport Ls 2wd, nd so the N started blinking on dash, nd it's like it is stuck in third gear when driving

The blinking neutral light does mean the transmission is overheating. There is a TSB (Technical Service Bulletin) out on the issue.

Just a couple of things before you try to have the dealer do this under warranty (it falls under the 6/60k)

1. The computer probably didn't record the overheat. So they'll tell you they can't just change out the pan.

2. The dealer probably won't take your car out and drive her enough to get it to overheat again (mine took about an hour and a half of solid highway speed) without you signing off on paying for the technician's time.

3. They're going to tell you the transmission was overfilled and that whoever checked it last checked it while it was in park instead of neutral (this is correct it should have been in neutral while in park and running it reads normal but when in neutral you will find it almost a quart overfull). I guess when it's overfilled the fluid foams up and doesn't do cover all of the parts as it should.

I had to call their corporate office and throw a fit because they didn't seem to believe I was having this problem and they wouldn't drive it to see it happening. To make a long story short, Corporate called the dealership and then the dealer called their warranty rep who just approved it.

The TSB reads that it is to correct transmission overheating in certain circumstances: heavy load AND overfull so you may want to bring that up it's always good to have some sort of backup.

My 2005 dodge neon jerks when i accelerate from a full stop.

There are a few different problem areas in your vehicle that come to mind as I was reading your complaint. I will go over the wire diagram for this neon and see exactly what we could be dealing with. Most importantly, I see your check engine light is coming on. If you can scan it while its on and get the codes I will be able to tell you pretty much exactly what is causing this jerking issue. Hopefully its a simple fix, could be under the hood, mechanical or electrical. Ive seen these pcm's fail in the past also. Advanced auto or autozone typically scans codes for free. Please Advise

I have a 2003 Chevy Silverado 4.3 Vortec, while the engine is under a load the check engine light will begin to flash and the truck will run rough for a very short period of time and also if it stores

what codes? will probably be a 300 - 308 or a lean code. need codes could be bad plugs or wires could be fuel filter or pump. without codes cant tell. also when check enging light flashes it means stop as engine or cat damage could result

Engine temporarily kick down under load, power quickly restored, engine light on since.

Stop at auto Zone or Advance Auto and ask them to read the stored codes and see what fault code you get. They will tell you what the code is and what it means and if you want it sell you the part.

My zafira pinks a bit when under load. is it the egnition timing, can it be adjusted.

This is a common problem with older cars ... sometimes it is as simple as upgrading to a higher octane fuel. If the issue is only occurring when driving with a load, then it is probably not a timing issue. Depending on the age of the vehicle, there might not be a solution to the problem. Older cars tend to face this issue, and would require a full engine rebuild to eliminate the noise (though it generally doesn't cause a HUGE problem for a long time -- I had an Escort that made a clinking noise under load for 5 years before I got rid of the car, and the only problem it caused was a little road rage about having to listen to it).
If the noise gets worse, you should probably bring it to a mechanic to make sure that there is not something more that can be done for you ... but if it is only occurring under load, and doesn't seem to affect the drivability of the vehicle, you shouldn't have to worry about it too much for now.

Recently had car serviced and cambelt replacement. came out of dealership gutless up to 2000rpm and then picks up, but not at full power. car is Focus 1.8 tdci 2003

take it back to the dealer and tell them they messed something up, that it is not working properly and they need to fix it!!!! I'm sure you paid a pretty penny to get the timing belt replaced, so take it back if it is not running right!

Did the shop say the belt was on wrong? I suspect it was, and possibly still is. They may not have known where the original position was and did it wrong again as Honda reference marks can be a little vague. If the belt was out enough to make the engine back fire, then it is possible that valves were bent however the fact that it idled fine is good news. Does it still idle fine? Bent valves will prevent a smooth idle, a compression test would be a good idea. I would take it to another shop, preferably a Honda dealer and have it checked again.

There are internal valve timing parts that are not operating correctly. Take it to a dealer to find out whether your warranty will cover the repairs.
